So Casey was up until the wee hours (after 4am) getting the site moved over to our new servers... but he must have had tired eyes because the login is broken for new members!
So sorry about that guys!
He came back to bed about a half hour ago so I am letting him sleep for a little bit before I wake him up to fix it.
Hang in there! He will take a look at it as soon as he is up.
More updates soon...
Casey's update: okay, things should be all fixed now. I am sending out copies of the invites that went out this morning so that people know that they can try again.
