Nice hack. It could be even better if instead of setting which usergroup it used it looked for the VB cookie and used the permissions based on the user registered. You used to be able to comment a line out in external.php to make it do this but it's not possible anymore. If you don't have a VB cookie i.e. your not a registered user it just basis the permissions on a guest login. This hack would be awesome if it could do that

- No pressure though... I would donate if it was made to work like this for sure.
