Hiya BrianG
I would've thought that your access would have been removed, unless something has not quite worked correctly
You could try registering your key again, then unregister it, just to see if that works. If it doesn't, I can contact an Administrator, to address this problem, or you can choose to 'Delete' your account (from your forum profile page). Deleting your account is permanent, and cannot be undone, but you can re-register with a new account if you want to. It's really up to you how you want to proceed
Regards.
Carl.
