Why a Warcraft Wiki?
Unlike a typical site were you have to wait for a small group of people to update the information as the world changes, WoWWiki allows users to contribute. As you're going through looking for information, if you see something that's incorrect, you can correct it. If you see any information that's missing, you can add it. This means WoWWiki is kept more up to date and accurate than other typical sites. The more people that use WoWWiki, the better better the quality and quantity of the information here will be!
WoWWiki, as with most wikis, operates under a set of policies that are adopted either by democrative vote by it's users or admins.
All users are free to enter their own policies or changes into the proposal process for users to comment and vote on.
