It seems an anti-spam plugin was causing some grief for new registrations, and so I've updated it. The registration agreement page, the first thing seen for new users, now includes a contact-the-admin link as well.
Sorry to the one or two guys who tried a dozen times to sign up. =)
It's all working well now, so that's alright! :)
I would suggest maybe adding the contact-the-admin link on the error page as well, unless it's a standard error page that you have no control over.
Mostly it's a matter of being lazy. Also, it's fixed, so I can't easily track that error. =)
Glad you made it through the gauntlet. Welcome aboard.
