Does Stack team app have forums? I don’t think they do. For example, Blackburn’s and LBOYB don’t seem to have anything that resembles the sort of forums that exists here. Neither does Facebook allow forums. It’s just one post after another.
I belong to a few other communities. One is using phpBB, which is a little dated in appearance but functionality is good. I think another is using Fora Communities, and has a more modern fresher look.
