"The specified username is currently inactive. If you have problems activating your account, please contact a board administrator."
"I registered but cannot login!
If you are sure the e-mail address you provided is correct, try contacting an administrator."
So the logic is... if there is a change of email address and the site does not send an activation email the logical next step is for that person to register an entirely new name so that contact can be made with a board admin?
