Hey Guys, How can I change the name of this article? The correct full title is A Sesame Street Mystery: The Case of the Missing Rara Avis -Radionate 04:59, 15 February 2006 (UTC)

If you're sure an article title is wrong, then simply do a move! At the top of the article page, after edit and history and so forth, there's a "move" tab." Click it (from the article page, not the talk page), enter the new name, type in the reason for the move if you like (it's optional, but comes in handy if someone wonders why you moved it), enter, and there you go. The original title becomes a redirect, but you can change the links to it on other pages as well. --Andrew, Aleal 05:11, 15 February 2006 (UTC)
