If I add a user to a group I gave him an automatic trust level 3.
But if I remove a member he remains to TL3.
IMO if a user has been removed from a group, his TL must returns to his natural TL (that can be TL3, of course).
I can do that manually, because our groups are little (max 20 users for the primary group).
But if I have to do the same thing for a very big community, manage each user individually become frustrating.
An user left our forum, I remove him from the primary group, after 73 days (last visit) he still have TL3.
But if I see the requirements:
Is it possible automatically remove a certain TL when a user has been deleted from a group?
