I'm not sure if this belong in "Wiki Projects" type stuff or not, so please forgive me.

My question is, is there any specific procedure, if one wanted to add a title (you know, when you press the little "?" next to a tag and it takes you to definitions of said tag) that one should follow? Should it contain a wiki definition for a title with no descriptions yet to be valid? Or dictionary terms? How should it be formatted (especially with related/aliased/implicated tags)? Should I leave that to moderators only, or can a peasant like myself add titles?

Sorry for the long question. Thanks!

If you change the title of the page, you'll make a different page. The title is part of the URL, after all, and the ? links to the URL with the same title.

What you can do is remove underscores and change capitalization. There's nothing wrong with that.

I thought the title said "Question About Titties"

The title of the page is always set to the tag name, and aliases/implications are automatically shown on the page. All you can or need to edit is the text of the page itself, which should simply be a description of what the tag is and when it should/shouldn't be used.
