Lucky you that you can get into the official forums, I would like to, but since I didn't play v1, I can't. :(
From the website when I try to login:
You could not log in because the service account in question is not registered.
If you would like to log in to the service, please log in to the Square Enix Account Management System and register the service account.
And code registration is disabled until the game is released I assume. Too bad they don't prospective players on the forum, but I understand it probably cuts down on spam, etc.
