Heya! A resource I tend to use a lot is WikiFur!
A.F.F's entry:
https://en.wikifur.com/wiki/Alt.fan.furry
If you are looking for other furry Usenet forums, there's:
alt.lifestyle.furry
alt.fan.albedo
alt.fan.furry.bleachers
Other than that, WikiFur will steer you in the right direction for finding more that I may not have listed!
