Okay, so avatars, sigs, etc., can be altered under Profile. Can I change my account name, too?
Oh, and also, I already checked under the FAQ, if it had any mention of changing account names, I must have missed it.

E-Mail Ryan, he'll change your name for you to what you want.

Thanks, but it's not a big enough deal to waste his time on. It's just that since I've mostly been posting as The Unknown Poster, I'd switch over to that name so folks can identify me more easily, assuming there were a quick and easy way. Oh well, thanks anyway.
