It's really not a new e-mail. Some skank has already taken "cocktaildoll" as a username. Actually, it's probably me from years ago and I forgot the password so I couldn't log into it. Or maybe it isn't me.
Anyway, do NOT use firstname.lastname@example.org (unless you're a spammer, in which case send all your e-mail there) because it's been screwed up for awhile and I can't figure out how to fix it.
