As a title says, not related closely or by far to GAF. So no off shoots and forums obsessing over GAF (no thebore self promotion!).
If further options are required then maybe not a forum overly obsessed with any issue/hobby but it can slant one way. GAF is too big for its own good, it feels too impersonal, I prefer smaller communities. GAF is too overly moderated, I'm an adult, I can deal with unpopular opinions. Pay forums suck. Is that enough?
