Forum:What is consensus?

My previous experience on wikis has just been editing fairly non-controversial articles. So for those of you who have done this sort of thing before, how do you know when a decision has been reached one way or another? How is this usually done? Is it done by committee? Does the person with bureaucrat privs make the final call? (Basically, I'm concerned I'll go cheerfully make some change I like, not realizing I'm really not supposed to have done that. I can get edit happy. :P) --mnenyver 21:49, 12 March 2008 (UTC)
