Chunbum Park is the current Featured Articles maintainer.

Note on editing Featured Articles (8 August 2011)

You are encouraged to fix any errors you find in our Featured Articles. Do note however, that changes made to the current Feature at CZ:Featured article/Current do not automatically apply to the main article. The /Current page is blanked once a week to make room for the next Feature. For your contribution to be permanent, you need to make the change in the main article as well, i.e. the topmost link in the list below. Thank you. Johan Förberg

Surely this should be made clear in other places than here? I continued editing one of the featured articles (Robert Burns) while it was still there, and I must have done it in the right way because the changes, as far as I can recall them, are still there. But it happened purely by chance. --Martin Wyatt 21:42, 15 February 2013 (UTC)
