User blog:Captain Moch/I'm in DESPARATE NEED OF HELP

Okay, at first: HEEEEEEELP! Secondly, I have no idea to change category names. At the top of categories, there is an edit, history, and stuff except no MOVE! I need to move Stories that Belong to User:Mochlum to Mochlum's Articles and Category:Irving: The Ultimate Phineas and Ferb Fan Club Promotional TV Show!!!!! and other categories for that changed to the show's new title Irving: The Phineas and Ferb Fan Club Show! So help me in comments (pretty please!)
