Is it really impossible to access the forums at all if you have forgotten your username? I have given up and created a new account under a different email address as I could not find a form to request a username reminder, and it is impossible to reset ones password if you do not know your username.
There is only one username linked to your email account so if you haven't sent an email to the above address yet do try to remember the email address from which you registered the old account.
