Why not run the clubs like clubs, but in a way that they self moderate? Let me
try (and probably fail) to clarify that point. You have your members and treat it like a normal thread while small and starting out until you get (quick think of random numbers
), say 25+ members, then the members vote in a chair. The chair hold the position for say 3 months, 100posts, 10 new members join, whatever pre-set point and everyone votes again on who's chair. The chair-person, if they accept their position, then takes on responsibility for moderating the thread and keeping the club's membership under control, but only in the club thread. Obviously, the clubs will be littering the relevant sub-forums that they are based in, so once you have an appointed chair, you move it into a clubs sub-forum, out of the way, and append the club to a list of clubs for fish in the sub-forum the club originated in, in a pined thread listing clubs for said sub-forum.
Obviously, this may not be implementable, and may have it's own complications. I'm not sure if you can set it up for a person to have mod privileges on one thread, so that part may, or may not, be possible. You'd also have to be able to ensure the chair didn't go on a deleting/editing spree in "their" club... Also, voting in a chair may be an issue, as might avoiding cliques within the club or the forum as a whole. However, it would allow "useful" clubs to remain open, self-contained and (possibly, depending on how voting in a chair, setting them up with privileges on one thread and the voting system works) low-maintenance from a moderators perspective. Also, the bigger clubs would be out of the way, while smaller ones can still fade into the distance...
That is however a complex solution to a simple problem. I would have no qualms if they were all just closed/deleted...
All the best
