Just a comment/idea for further improvement:
our Discourse has separate categories linked to groups representing separate community membership. There are multiple communities on the same overall installation. It would be good if
- either the “user to user inivitation” includes an automatic option so that the invitated person inherits the same group membership as the invitating person (maybe selectable if the inviter has multiple group memberships)
- or there is some kind of workflow where the admin/moderator approval adds the correct group permissions in a second step
