Just chipping in here
@Nowler as I just spotted your thread. So it really depends on whoever managed the private forum, if a forum goes quiet, I'll ask whether they want to keep it going, archive it and open it up to everyone, or archive it and keep it closed. It's up to them, as they've requested and managed it, and members have posted there with the understanding it's a closed group. So unless the person who's managing it agrees to it, unfortunately there's not a lot we can do. Most will just want to mothball it but keep it available to existing members. What I need to do is update the descriptions of the archived forums as they appear to still be open to apply to join when that isn't the case. I'll remove those links now.
