Ah, looks like he didn't actually register, but went straight to "log in", and entered the username, and no password (Or the registration just didn't go too well). That caused some freaky bad stuff to happen, in that he was only half registered, and then only on that board. I've fixed it so that it can't happen again.
If you could get him to visit http://bb.bbboy.net/register.cgi
if you manage to catch his attention on straightdope
Once he's registered, if post count is important, just get him to let me know what it should be, and I'll set it for him...
