Ok, thanks to our stupid host, even though we've figured out the problem and the solution, it can't be fixed until after Christmas. Long story.
Meanwhile, I've deactivated the activation email system. So people can register immediately, until we get this fixed.
That means some more spam than usual might sneak through. Moderators, please remember to just leave the spam alone and unapproved, and I'll deal with it when I get here. I'm feeling so much better now, so I should be around almost as much as usual, and getting better fast.
Once again, I apologize for the inconvenience.
