Hi, I have permissions set up so that when a user registers, they have no access to any forums. Is there any way to notify a user when I do (or do not) grant a user permissions to a forum?
I'd suggest you use the wpForo Private Messages (PM) addon to notify the users when you do grant a user permissions. All you need is having a standard text you should send the users each time.
The add-on also allows the members of your forum to communicate directly with each other. Besides, it allows multi-member conversation and other managing tools.
