What are “Community Wiki” posts?
Every question I ask offers me the chance to designate it "community wiki". I do not because I don't know what "community wiki" is.
I see that there is lots of discussion on whether "community wiki" should exist, and if so, how to use it properly. I do not want to get into that discussion.
I would like to know what the official (if hotly argued) explanation of "commmunity wiki" is. Is there a link to it somewhere?
