Apparently he tried to change his email account. Doing so caused the system to send him an activation email to his new mail account - he can't log in until he sends the activation link back to the website. Only problem is, the activation email never got to his email account, so he can't re-active his account . . . and apparently he can't even get *any* activation emails, even to a brand-new account. So I've contacted on of the mods on his behalf and we'll see what happens.
