I have recently received a message from a potential user trying to register onto to site. This is a message to that user and to any other guests who are having trouble becoming a part of our site. I suggest trying to register again with a different email, say like with a gmail account. If that doesn't fix it, make sure you're typing in the password and username you registered with. If you have any other question please comment here and I'll try to help you out as best as I can.
