All you have to do is put [[Category:<name of category>]] into an article and it will add it as a category for the article automatically; so for example, if you wanted to put the category "Cats" onto your article, you'd put [[Category:Cats]] in the article itself, or use the box to the right of the editing screen (don't put the "Category:" thing with it though, just the name of the category).
You should make sure the category you want doesn't already exist though before making it, though.
Well... technically, yes, but we do have regulations concerning them. For example, you can't just take a character from a different franchise and throw them into the Sonic universe as they are.
Typically what people do is make a Mobian character that's based upon a character from a different franchise, and effort should be taken to not make them exactly like the character from the different franchise with the only difference being species.
This guy has posted porn and has a hateful user name. When you get a chance, I'd like if you would block them and delete their content. (Also, given the frequency of vandalism on the site, you might want to consider an IP ban for one or more of these vandals. You don't have to, of course, but it might help.) (Never mind, I just noticed that you actually have been IP blocking these people. Thank you.)
