I just recently installed this add on (didnt update the step to use VB for comments yet) and I was sent a message from a guy saying he was not able to register. So I gave it a run myself, and I could not register a new account on the forums anymore either.
The forum is located here

Right after you input your date of birth and go to accept the TOS is says "You have left a required field blank." But there are no fields other than clicking the check box which is being done.
Can anyone give this a look and let me know what happened?
