Okay. Will do. Your current username will be "banned" and you can sign-up with a new name.
May I suggest that you mention in your signature line (or under your avatar) that you are the poster previously known as "Anaxagoras1986"? At least for a while until folks figure out who you are again.
I can't do that as a mod, but I will refer your request to Admin. We usually simply "ban" the old account and folks start a new one. I've never had anyone mention the difficulty with e-mail...hmmm. But it does seem you've been able to sign-up again, no?
