BuddyPress.org

Hi, i’m involved into a new open source software and I like the way the Codex runs here.
Could someone explain me how it works ? I would like to have something similar on my website…

I found this informations :

John James Jacoby of BuddyPress.org has announced that the BuddyPress Codex has received a much needed refresh. Here is the kicker, the BuddyPress Codex is powered by a WordPress installation where all registered users are an editor. Users can share information as in a traditional wiki but everything is housed on individual pages. Interestingly enough, this very idea was proposed a couple of times during the past few years for the WordPress Codex but it never gained much traction.

Thanks for informations !
