You have to be a chat moderator or administrator to do that (or less commonly, VSTF, Wikia Helper, or Wikia Staff).

On Community Central, chat moderator/administrator positions are chosen by Staff from the best, most helpful, veteran members of the community. But other wikis generally make it a lot easier to get the rights, and if you create a wiki, you're automatically an admin.
