'''''Second Life''''' (abbreviated as '''''SL''''') is an [[Internet]]-based [[virtual world]] which came to international attention via mainstream news media in late 2006 and early 2007.<ref>{{cite news |first=Irene |last=Sege |title=Leading a double life |url=http://www.boston.com/news/globe/living/articles/2006/10/25/leading_a_double_life/ |work=[[The Boston Globe]] |date=25 October, 2006 |accessdate = 2007-02-15 }}</ref><ref>{{cite news |first=James |last=Harkin |title=Get a (second) life |url=http://www.ft.com/cms/s/cf9b81c2-753a-11db-aea1-0000779e2340.html |work=[[Financial Times]] |date=17 November, 2006 |accessdate = 2007-02-15 }}</ref> Developed by [[Linden Lab|Linden Research, Inc]] (commonly referred to as Linden Lab), a downloadable [[Client (computing)|client program]] enables its users, called "[[Resident (Second Life)|Residents]]", to interact with each other through motional [[avatar (icon)|avatars]], providing an advanced level of a [[social network service]] combined with general aspects of a [[metaverse]]. Residents can explore, meet other Residents, socialize, participate in individual and group activities, create and trade items ([[virtual property]]) and services from one another.
'''Second Life''' (SL) is a multi-user virtual environment (MUVE) created by the San Francisco (USA)-based Linden Lab in 2002. A consumer version of the software was released in 2003.<ref>{{cite news |first= Linden Lab |title=Linden Lab Announces Name of New Online World Second Life(TM) and Availability of Beta Program |work=PR Newswire |date=30 October, 2002 |accessdate = 2007-10-29 }}</ref> From the first press release (30 OCT 2002):  


''Second Life'' is one of several virtual worlds that have been inspired by the [[cyberpunk]] literary movement, and particularly by [[Neal Stephenson]]'s novel ''[[Snow Crash]]''. However, Second Life is in a virtual world class of its own. The stated goal of Linden Lab is to create a world like the [[Metaverse]] described by Stephenson, a user-defined world of general use in which people can interact, play, do business, and otherwise communicate.<ref name="usatoday-rosedale-interview">{{cite web|

"Using new technology to enable a dramatic leap forward in the self-expression possible in a 3D online world, we have created a new experience that is, in nearly every sense of the words, a Second Life," said Philip Rosedale, CEO and founder of Linden Lab. "Our residents create a new identity in a world that they shape -- whether vixen or villain, architect or explorer. With early creators spending as much as 60 hours a week in-world, we believe Second Life is poised to revolutionize the online experience."

}}</ref> ''Second Life''<nowiki>'s</nowiki> virtual currency is the [[Economy of Second Life|Linden Dollar]] (Linden, or L$) and is exchangeable for US Dollars in a marketplace consisting of residents, Linden Lab and [[real life]] companies.
While ''Second Life'' is sometimes referred to as a [[game]], this description is disputed. It does not have points, scores, winners or losers, levels, an end-strategy, or most of the other characteristics of games, though it can be thought of as a game on a more basic level.  It is a semi-structured virtual environment where characters undertake activities for the purpose of enjoyment.


In all, more than six million accounts have been registered, although many are inactive, and some Residents have multiple accounts. Despite its prominence, ''Second Life'' has notable competitors, including [[Weblo.com]], [[Active Worlds]], [[There (internet service)|There]], and newcomers such as [[Entropia Universe]], [[Dotsoul]] Cyberpark, [[Red Light Center]], and [[Kaneva Game Platform|Kaneva]].
''Linden Lab reported 1,000,000 registered users in ... and passed 10 million registrants in...''


==Features of the virtual world==
===User Interface and Interaction===
Anyone can create a free Second Life account, and one can download the free client program (approximately 32 MB). ''...include screen shot...'' The computer-based embodiment of a person on the screen is known as an "[[avatar]]." ''Second Life refers to its users as "residents."


===Residents===
Second Life is not a game in the traditional sense, in that there are no objectives to reach except those the user sets for him or herself. There is no system of points, levels, scores, and no overall strategy guides ones in-world interaction. Instead, the program is primarily social and provides a good deal of opportunity for economic interaction. Except for the basic elements of "land" and "sky," all content in Second Life is user-created, including clothing for avatars, buildings, roads, spaces for exploration, etc.
{{main|Resident (Second Life)}}


''Residents'' are the users of ''Second Life'', and their appearance is their ''[[Avatar (icon)|avatar]]'' (often abbreviated to ''av'' or ''ava''). The basic avatar is human in appearance, but avatars may be of either sex, have a wide range of physical attributes, and may be clothed or otherwise customized to produce a wide variety of humanoid and other forms. A single person may have multiple accounts, and thus appear to be multiple Residents (a person's multiple accounts are referred to as ''[[Alternate character|alts]]''). However, the use of additional accounts requires the Resident to register them and pay a small fee, though after May of 2006, there is no verification process preventing users from creating multiple "first" accounts using false information, a common practice. Also, a single Resident's appearance in ''Second Life'' can vary dramatically at will, as avatars are easily modified.
===Economics of Second Life===
Linden Lab created an economic system in Second Life through which residents buy and sell services and virtual representations of items (clothing, homes, cars, etc.). The monetary unit is the Linden Dollar (L$), which is worth approximately US$0.33.  


===Communication and transport===
===Education in Second Life===
Within ''Second Life'', there are two main methods of text-based communication: local chat, and global "instant messaging" (known as IM). Chatting is used for public localized conversations between two or more avatars, and can be "heard" within 25&nbsp;m. Avatars can also 'shout' ('audible' within 96&nbsp;m) and 'whisper' ('audible' within 18&nbsp;m). IM is used for private conversations, either between two avatars, or between the members of a group. Unlike chatting, IM communication does not depend on the participants being within a certain distance of each other. Voice communication is currently in beta testing.
Two sources with a good deal of information about educational efforts in Second Life include:
* SimTeach Wiki
* SLEDucation Wiki
See ''External Links'' subpage for the websites.


The most basic method of moving around is by foot. To travel more rapidly, avatars can also fly up to about 170&nbsp;m over the terrain (meaning 270&nbsp;m if ground level is 100&nbsp;m, 180&nbsp;m if ground level is set to 10&nbsp;m) without requiring any special equipment, and with scripted attachments there is currently no limit to how high an avatar can fly (although once past several thousand meters, the rendering of the avatar mesh starts to be affected).
===Media Coverage===
''(major articles about SL go here)''


Avatars can also ride in vehicles; many vehicles are available &mdash; there is a basic [[go-kart]] contained in the object library and there are many Resident-made vehicles available freely and for purchase including helicopters, submarines and hot-air balloons. Airborne vehicles can fly up to about 4000&nbsp;m high (the maximum altitude allowed for any object).
===Competition===
* Active Worlds
* Weblo.com
* There
* Entropia Universe
* Dotsoul Cyberpark
* Red Light Center
* Kaneva


For instantaneous travel, avatars can teleport (commonly abbreviated to "TP") directly to a specific location. An avatar can create a personal landmark (often called an LM) at their current location, and then teleport back to that location at any time, or give a copy of the landmark to another avatar. There's also a map window that allows direct teleportation anywhere.
Sun Microsystems has created its own virtual world in which its employees can interact, and many other corporations are doing the same.


There are some external websites that allow Residents to locate each other from outside of the virtual world, and [http://slurl.com SLurl.com] allows external links through the ''Second Life'' World Map to locations in-world.

''Second Life'' has its own economy and a currency referred to as Linden Dollars (L$). Though the exchange rate fluctuates, as of February 2007 it is reasonably stable at around L$ 270 to one [[United States dollar|US dollar]].<ref>{{cite web |url=http://www.secondlife.com/whatis/economy-market.php |title=LindeX Market Data |accessdate = 2007-02-22 |date=2007-02-22 |publisher=[[Linden Lab]]}}</ref>
 
Residents create new goods and services, and buy and sell them in the ''Second Life'' virtual world. There are also currency exchanges where Residents can exchange US$ or other real world currencies for L$. These exchanges are open markets, except that Linden Lab sometimes changes in world Linden Dollar "sinks" or sells Linden dollars to attempt to keep the exchange rate relatively stable. A small percentage of Residents derive net incomes from this economy, ranging from a few hundred to several thousand US$ per month, while a larger percentage derive a gross income large enough to offset most of their expenditures in L$. The currency has become the subject of concern in economic circles in regard to possible [[taxation]].<ref>{{cite web

Premium members can own land (up to 512&nbsp;m² without additional fees). Owning larger areas of land incurs an additional fee (which Linden Lab calls "tier") ranging from US$5 a month up to US$295 a month for an individual island.<ref name="secondlifedotcom-land-pricing">{{cite web|

The only exception to this is land purchased in "private sims" or "private islands", which are governed by Residents and not Linden Labs. These private islands have what are called covenants that may restrict use of the land, such as prohibiting any commercial activity, or even resale of the land itself.
 
===Creation and copyright===
One of the distinguishing characteristics of ''Second Life'' is that the Residents, not Linden Lab, create most of the content of the world. The Resident avatars are one example of such [[user-generated content]].
 
There is a 3D modeling tool in ''Second Life'' that allows any Resident with the right skills to build virtual buildings, landscape, vehicles, furniture, and machines to use, trade, or sell. This is a primary source of activity in the economy. Any Resident can also make ''gestures'' from small animations and sounds from the standard library. Outside ''Second Life'', Residents can use various graphics, animation, and sound tools to create more elaborate items, and upload them into the world. Once the creation is in the world of ''Second Life'', the system makes efforts to help protect the exclusive rights of the ''content creator''.
 
''Second Life'' also includes a [[scripting language]] called [[Linden Scripting Language]], or LSL. LSL is used to add autonomous behavior to many of the objects in ''Second Life'', such as doors that open when approached. LSL has been used to create relatively advanced systems, such as the [[artificial life]] experiment on the island of Svarga, where a complete ecology runs autonomously (including clouds, rain, sunshine, bees, birds, trees and flowers).<ref>{{cite web |url=http://nwn.blogs.com/nwn/2006/05/god_game.html |title=New World Notes: GOD GAME |accessdate = 2007-03-03 }}</ref>
 
When objects are created (or instantiated) in-world and then transferred to the Resident's computer, they are said to "[http://slhistory.org/index.php/Rez rez]" &mdash; a reference to the Disney movie ''[[Tron (film)|Tron]]''. This also appears in LSL, where the command to create an object is ''llRezObject()''.<ref name="lslwiki-llRezObject">{{cite web|

title=LSL Wiki: llRezObject()|
publisher=LSL Wiki|
accessdate = 2006-11-25|
}}</ref>
 
A Resident who creates an item and the Resident that owns an item may retain certain rights, simulating and in some ways enhancing the [[copyright]] available in the real world. The creator can mark an item as "no copy," which means that no copies of it may be made by others, "no mod," which means that others may not modify the item's characteristics, and "no trans," which means that the current owner may not give it to another.
 
Live music performances take place in ''Second Life'', in the sense that vocal and instrumental music by ''Second Life'' Residents can be provided from their homes and studios. This is played into microphones, uploaded to audio streams, and played in-world for the enjoyment of other Residents. This started with performances by Astrin Few in May 2004<ref name="SL-live-music-musicians">{{cite web|

===Arts and creativity in ''Second Life''===
Many of the (initial) residents of ''Second Life'' have a creative background. There is a large virtual community of artists and designers. They use Second Life not only as platform to demonstrate their art from real life, but also to express themselves and create new (virtual) art. The virtual creations from the [[metaverse]] are disclosed in real life by initiatives such as Fabjectory (statuettes)<ref>{{cite web |url=http://www.fabjectory.com/index.php/secondlife/ |title=Fabjectory |accessdate = 2007-05-06}}</ref> and Secondlife-Art.com (oil paintings)<ref>{{cite web |url=http://www.secondlife-art.com/ |title=Secondlife-Art.com: real life paintings from Second Life |accessdate = 2007-03-02}}</ref>. The modeling tools from Second Life allow the artists also to create new forms of art, that in many ways are not possible in real life due to physical constraints or high associated costs. The virtual arts are visible for example in the Second Life Louvre, a virtual representation of the [[Louvre Museum]].

===Education in ''Second Life''===
''Second Life'' has recently emerged as one of the cutting-edge virtual classrooms for major colleges and universities, including Harvard, Vassar, Pepperdine, University College Dublin, Elon University, Ohio University, Ball State, New York University, University of Houston, Stanford University, Delft University of Technology<ref>{{cite news |first=Tomas |last=van Dijk |title=TU koopt grond in Second Life (Dutch)|url=http://www.delta.tudelft.nl/archief/j39/n7/21781 |work=[[Delta (TU Delft)|Delta]] |date=2007-02-22 |accessdate = 2007-02-24 }}</ref> and [http://www.afeka.ac.il/siteFiles/2/1/1003.asp AFEKA Tel-Aviv Academic College of Engineering].<ref>{{cite news |first=Leo |last=Natan |title=Center for Internet, Metaverse and Society|url=http://www.afeka.ac.il/SiteFiles/2/11/1120.asp |date=2007-03-19 |accessdate = 2007-03-19 }}</ref> ''Second Life'' fosters a welcoming atmosphere for administrators to host lectures and projects online, selling more than 100 islands for educational purposes, according to a ''New York Times'' article.<ref>{{cite news |first=Christine |last=Lagorio |title=The Ultimate Distance Learning |url=http://www.nytimes.com/2007/01/07/education/edlife/07innovation.html |work=[[New York Times]] |date=2007-01-07 |accessdate = 2007-02-14 }}</ref> The article quoted Rebecca Nesson, an instructor at [[Harvard University|Harvard]] who brought her Legal Studies class to ''Second Life'' in the second half of 2006. "Normally, no matter how good a distance-learning class is, an inherent distance does still exist between you and your students," she says. "''Second Life'' has really bridged that gap. There is just more unofficial time that we spend together outside of the typical class session." Joe Sanchez, a researcher at the University of Texas at Austin evaluated the use of Second Life in education in an interactive qualitative analysis, finding that once students overcome the technical and interface difficulties with Second Life, they "indicate a preference to social learning activities and find it enjoyable to interact with other avatars while learning in this space".<ref>{{cite news |first=Joe |last=Sanchez |title=Second Life an Interactive Qualitative Analysis |url=http://www.aace.org/conf/site/sessions/index.cfm/fuseaction/PaperDetails?CFID=1384538&CFTOKEN=96722631&presentation_id=31844 |date=2007-03-07 |accessdate = 2007-03-07 }}</ref>
 
Among the more active educators in Second Life are librarians. The Illinois' [[Alliance Library System]] and OPAL have teamed up to extend the programs currently offered online to librarians and library users within Second Life. There are numerous libraries within what is referred to as the Info Islands. A virtual reference desk in SL is staffed by real life volunteer librarians for many hours every week. They also teach workshops there to help librarians and educators learn more about Second Life.
 
Late in 2006, a trend emerged whereby large consortia purchased several islands comprising an archipelago of education-focused land. The land is then subdivided into smaller parcels and rented to colleges, universities, and educational projects. Typically, land is  rented for as little as $200 per year and comes with permission to use some common space for larger events. Two prime examples are the Info Islands, which includes EduIsland I and II, and the [[New Media Consortium]]'s NMC Campus which includes many Teaching Islands and a wide range of educational tools, services, and meeting spaces, a museum and library, and a planetarium. The consortial model has allowed for many more institutions to offer participation to students and faculty within a learning-centered environment.  As a result, there are now hundreds of [http://www.simteach.com/wiki/index.php?title=Institutions_and_Organizations_in_SL#UNIVERSITIES.2C_COLLEGES_.26_SCHOOLS colleges and universities] experimenting with Second Life.
 
==Pricing==
''Pricing'' determines what residents pay to Linden Lab, and is separate from the Second Life economy  where residents buy and sell to each other.
There are two types of accounts, ''basic'' and ''premium''. Basic accounts have no recurring fee, but lack the right to own land within ''Second Life''. Premium accounts pay US$9.95 per month, as of February 2007.<ref name="secondlifedotcom-membership-plans">{{cite web|

==''Teen Second Life''==
{{main|Teen Second Life}}
''Teen Second Life'' was developed in early 2005 to enable people aged 13-17 to play ''Second Life'' without entering false information to participate in the Main Grid. Both Grids at that time required the entry of credit card details, but the Main Grid made it mandatory that the credit card be the Resident's own, whereas the Teen Grid made it mandatory that it belonged to a parent. (Since then, the requirement for a credit card to register on the Main Grid has been removed. Also, for players in some but not all countries, a parent's credit card is no longer required to register on the Teen Grid, only a valid cell phone with SMS enabled.)
 
New (voluntary) identity/age validation measures are also being proposed to further secure the distinctions between "PG" and "mature" regions on the main grid, ensuring that only validated adults can enter the latter.

The policy change to email-address-based membership brought about harsh criticism.  The resultant flood of new members (most of them non-paying users) overtaxed the system both in hardware and manpower, causing excessive lag, teleportation and inventory failures, a dramatic increase in "griefing" and other problems.  Allegedly to attract corporate interest, Linden Lab posted a public blog patting themselves on the back for reaching the "2 million residents" mark.  This was met by numerous angry criticisms pointing to degraded system performance as a result.  Several users noted that the claimed "residence" figures were highly exaggerated, pointing out that the actual activity of the board was roughly nine percent of the claimed residency figures, with paying membership below the two percentile point.  Blogs and forum posts regularly attack the company for making exaggerated membership and performance claims.
http://blog.secondlife.com/2006/12/14/ill-see-your-million-and-double-that/  There is also considerable criticism regarding paying members footing the bill for countless "freebie" users, while themselves receiving no preferential treatment or increased system performance. Free users have countered they "contribute" to the system just by their presence, some making claim of significant contribution via "time and content".  Paying users counter that "playing a game" does not constitute contribution to the system.  Debate regarding this issue has been drawn-out and heated, with advocates and critics on both sides of the issue.
 
In January 2007, two articles were published on the Internet which compared the economy of Second Life to a [[pyramid scheme]].<ref>{{cite web |url=http://randolfe.typepad.com/randolfe/2007/01/secondlife_revo.html |title=SecondLife: Revolutionary Virtual Market or Ponzi Scheme? |accessdate = 2007-02-14 |last=Harrison |first=Randolph |date=23 January, 2007 |work=Capitalism 2.0}}</ref><ref>{{cite web |url=http://valleywag.com/tech/second-life/virtual-worlds-supposed-economy-is-a-pyramid-scheme-230813.php |title=Virtual world's supposed economy is 'a pyramid scheme' |accessdate = 2007-02-16 |date=January 23, 2007 |work=[[Valleywag]]}}</ref> In the same month, a "virtual riot" erupted between members of the French party [[National Front (France)|National Front]] who had established a virtual HQ on Second Life, and opponents, including Second Life Left Unity, a socialist and anti-capitalist user-group.<ref>{{cite web |url=http://nwn.blogs.com/nwn/2007/01/stronger_than_h.html |title=Fighting the Front |accessdate = 2007-02-14 |last=Au |first=James Wagner |date=15 January, 2007 |work=New World Notes}}</ref><ref>{{cite web |url=http://games.slashdot.org/article.pl?sid=07/01/17/2145241 |title=Political Strife Erupts in Second Life |accessdate = 2007-02-14 |author=Zonk |date=17 January, 2007 |work=[[Slashdot]]}}</ref><ref>{{cite web |url=http://www.stuff.co.nz/stuff/3940079a28.html |title=Virtual race war unsettles Second Life |accessdate = 2007-02-14 |last=Hutcheon |first=Stephen |date=25 January, 2007 |work=Stuff.co.nz}}</ref><ref>{{cite news |first=Oliver |last=Burkeman |title=Exploding pigs and volleys of gunfire as Le Pen opens HQ in virtual world |url=http://www.guardian.co.uk/france/story/0,,1994882,00.html |work=[[The Guardian]] |date=January 20, 2007 |accessdate = 2007-02-14 }}</ref> Since then, several small internet based organizations have claimed some responsibility for instigating the riots.<ref>{{cite news |first=Ghaz |title=How to start a riot in second life |url=http://forumite.com/index.php?subaction=showfull&id=1171633707&archive=&start_from=&ucat=5& |work=forumite.com |date=February 16, 2007 |accessdate = 2007-02-16 }}</ref>
 
There are also issues with SecondLife support being under resourced, with support tickets and billing issues going unresolved. Residents have complained of having money stolen from their accounts, having credit withdrawals fail and other related billing issues.
 
During 2006 several established members of Second Life ceased support of the system.  Among these was Starrax, SL's most popular sculptor and builder/scripter.  Premiere live musician Astrin Few publicly posted a stern warning of intent to leave the system if host company Linden Lab did not pay more attention to customer needs.  Criticisms against host company Linden Lab involve continuing system technical issues such as lag, repetitious bugs, customer inventory loss and excessive downtimes.  Also cited were issues regarding "self-serving" company policies, failure to police the system (including lack of protection of members from alleged unethical/criminal activities), and criticism of host company Linden Lab for gross misrepresentation of membership figures.  The late 2006 exit of the Elven Lord Wayfinder Wishbringer and the subsequent decision of the Elf Clan Counsel to shut down lands and cease financial support of the Second Life platform was a negative milestone that created significant ripples.  The group cited as primary cause for shutdown the host company ignoring misappropriation by a renegade officer of thousands of dollars in group funds and lands-- a common criticism of Linden Lab policies.
 
The same time period brought strong criticism against Linden Lab for their allegedly catering to big business and ignoring the people and groups who had helped them build the system.  Such criticism increased dramatically when Linden Lab in anticipation of corporate investments increased first year costs of private virtual islands by some 32% and second year rentals by 50%, making it difficult for hobbyist users to afford such fees.
 
First year costs of private islands are $1,695 purchase price and $295 a month maintenance fees, for total first-year costs of $5,235 USD.  It has been pointed out that such costs are equal to or in excess of purchasing an acre of land in real life.  Second year land costs total $3,540, far in excess of any conceivable real life property taxes.

===Software===
The ''Second Life'' software comprises the ''viewer'' (also known as the ''client'') executing on the Resident's computer, and several thousand servers operated by Linden Lab. There is an active ''beta-grid'' that has its own special client, which is updated very regularly, and is used for constant software testing by volunteers. This testing software was introduced to eliminate the short amounts of time between real updates, and increase its overall quality. The beta-grid reflects the standard main-grid, except that the actions taken within it are not stored by the servers, it is for testing purposes only. Every few months, the standard software is replaced by the beta-grid software, intended as a big upgrade. The ''Second Life'' user-base is growing rapidly, and this has stimulated both social and technological changes to the world; the addition of new features also provides periodic boosts to the growth of the economy.

Linden Lab provides viewers for Microsoft Windows, Mac OS X, and most distributions of Linux. Viewer upgrades are usually mandatory; the old viewer will not work with the new version of the server software. However, Linden Lab is working on a more flexible protocol that will allow clients and servers to send and take whatever data they may require, hence differing versions would nonetheless be able to work together.
 
As of January 8, 2007, the Viewer is distributed under version 2 of the [[GNU General Public License]],<ref name="lindenlabdotcom-press-release-01-08-07" /><ref name="lindenblog-embracing-the-inevitable" /> with an additional clause allowing combination with certain other [[free software]] packages which have otherwise-incompatible [[free software license|licenses]]. Currently not all of the required dependencies have been released. See [https://wiki.secondlife.com/wiki/Open_Source_Portal] for details.

This article is about Second Life, the multi-user environment. For other uses of the term Life, please see Life (disambiguation).

Second Life (SL) is a multi-user virtual environment (MUVE) created by the San Francisco (USA)-based Linden Lab in 2002. A consumer version of the software was released in 2003.[1] From the first press release (30 OCT 2002):

"Using new technology to enable a dramatic leap forward in the self-expression possible in a 3D online world, we have created a new experience that is, in nearly every sense of the words, a Second Life," said Philip Rosedale, CEO and founder of Linden Lab. "Our residents create a new identity in a world that they shape -- whether vixen or villain, architect or explorer. With early creators spending as much as 60 hours a week in-world, we believe Second Life is poised to revolutionize the online experience."

Linden Lab reported 1,000,000 registered users in ... and passed 10 million registrants in...

User Interface and Interaction

Anyone can create a free Second Life account, and one can download the free client program (approximately 32 MB). ...include screen shot... The computer-based embodiment of a person on the screen is known as an "avatar." Second Life refers to its users as "residents."

Second Life is not a game in the traditional sense, in that there are no objectives to reach except those the user sets for him or herself. There is no system of points, levels, scores, and no overall strategy guides ones in-world interaction. Instead, the program is primarily social and provides a good deal of opportunity for economic interaction. Except for the basic elements of "land" and "sky," all content in Second Life is user-created, including clothing for avatars, buildings, roads, spaces for exploration, etc.

Economics of Second Life

Linden Lab created an economic system in Second Life through which residents buy and sell services and virtual representations of items (clothing, homes, cars, etc.). The monetary unit is the Linden Dollar (L$), which is worth approximately US$0.33.

Education in Second Life

Two sources with a good deal of information about educational efforts in Second Life include:

  • SimTeach Wiki
  • SLEDucation Wiki
