How about a sidespin forum?, a center ball forum? A Duckie forum where every post he makes is moved there.
A what's wrong with pool forum? That topic comes up every couple weeks.
And put that together with the How to Fix Pool forum.
How about a Knocker's and Nits forum? If you want to knock or be a nit then your posts go there where you can commiserate with all the other knockers and nits. Be like the old barbershops where the old men would sit around and complain about the world all day.
And we definitely need a TOI Blows everyone Away Forum since that's a favorite thing for some people to post. We never get tired on the predominately pool forum of being reminded of how great TOI is, how much money TOI players make, how great of cueists they are, how smart and handsome they are, and how they were running Racks before they got to kindergarten because just by virtue of being TOI players they are infinitely more talented than non TOI pool players.
Which leads to the next subforum, the Talent vs Training Subforum. That subject always generates a lot of debate and certainly should be relegated to a subforum.
I personally would like to see a subforum dedicated to the 2 ball. I like the two ball because it's blue and I like blue so we should have a forum for that. In fact let's just have 15 new forums for all the balls. Ooops 16 because of course we can't forget the cue ball.
