Where does all this come from?
The way community wiki's work (wikis like WoWWiki and Wikipedia) is that everyone who reads them can effectively edit anything in them. If you're looking at the strategy for Zul'Jin and see something that's not right, or that needs to be added, you can do it right on the spot. Of course you have to sign up for an account and make sure what you're putting in is correct, but that takes all of five minutes. User submitted content is critical to the success of a wiki, and WoWWiki is (as I'm sure most of our readers would agree) one of the most successful game wikis out there.
