While testing registration, I ran into a couple of odd time-out issues. I'd fill everything out and submit, and then it would go into a long delay and then give a database error.
Unfortunately, SMF only allows you to register from the same IP twice before it decides that you're doing stuff that you shouldn't, and so I was unable to do any more testing.
What I did find is that although it times out and gives you an error message, it does seem to work. You should get an email that your registration is pending.
Once you're on the forum, please go to:
