Please refrain from adding useless categories to pages. The categories on pages are fine as they are and, in most cases, the templates add the needed categories anyway. "B-Daman" and "Last episode of the first CrossFight series" are just pointless.
Furthermore, make sure your Trivia is notable and interesting, and perhaps something that wasn't previously known. The Trivia you added was quite basic and unneeded.
Sorry! I'm not trying to be mean at all, I'm just trying to advise you on how to be a better editor as all.
Before I forget, you wanted your userpage locked? Are you aware that that would mean you couldn't edit it either?
