Yeah, that works just nifty. My boards and PhotoPost are stock too! Here's the odd thing, (on my site) if I try to log in using an existing user name from my forums, I get the error. I THOUGHT the install and integration was supposed to bring over the database from the forums. I obviously did something wrong. I CAN create a new user though. The PhotoPost register link brings me to the UBB registration page. It the existing users that don't work so good.
