I am using Subscribe2 on a BuddyPress site and I am trying to keep posts from being sent to a specific group. I am wondering if it's possible to deselect "compulsory categories" by user (which I would do for each user in that group)? Right now when I try to do this the categories are checked and grayed out. It seems compulsory categories are checked by default for Registered Subscribers. Is there a workaround to this that you can see? Any help is appreciated!
