From Jullias's welcome message (on the Announcements board):

If you signed up for an account on our previous public forum, all of those accounts have been transfered over in some form. However, we were unable to transfer the password between the two due to different formats. When you click the Login icon at the top, simply follow the forgot your password link and you will receive a password in the mail. If you've tried every email address you can remember and still can't get your password mailed to you, drop me a note at jullias@carrionfields.com and I will take care of it for you.

We're sorry you've had so much trouble. I'm sure Jullias will be happy to resolve it quickly.
