Okay. Let me give you a registration webpage that I dug up. It may be the only webpage for that. Anyway, it's
http://dsd-guide.com/user/register.
After I signed up, I got a webpage that said, "A validation e-mail has been sent to your e-mail address. You will need to follow the instructions in that message in order to gain full access to the site."
That's as far as I've gotten so far.
