... but pages are not renamed on a whim. If you feel a page needs to be renamed, propose the rename on the forums, where it will be discussed and a consensus reached. If the consensus is to rename, then it will be renamed.
This is not to say the name you changed it to was bad. I agree, it's probably better. But we have procedures here, and we have had to ban at least one person who simply could not or would not accept that no one but him wanted the renames that he tried to impose on the wiki. You've been a member here for over three years, you should know this. I'm not going to penalize you -- no tempban or anything -- just a warning. Do this the right way.
