I suggest requesting this here. That's the contact page, and will probably be more useful than to request it in the Forums. Really, none of the Admins except Carlie (The Community Admin) look here, and they're the people you want to talk to.
Or, simply leave the site without logging on ever again. Funnily enough it kinda does the same. Just with the fact that could be found, instead of a 404, but the name cannot be used again, and all
