I have tried to sign up for an account using my old twitter tag (sadly/not sadly banned.) When I got to the 'verify account' stage, it gave me an error saying my username was already taken, which is really unique to me, so I don't see it as being a common username that would be already taken by anyone else but me.
I tried to request a 'password' reset, entered in my email,.. and not have not yet received the email to do so. (It's been over 5 hours.)
Has anyone else had similar issues with signing up?
