If memory serves me, after the Fly Fish Alberta (FFA) forum closed, everyone dispersed and it seemed the guys in the south predominantly went to Fly-Fish Calgary (FFC).
Up north there was Northern Lights Fly-Tyers (NLFT) and Alberta Outdoorsmen (AO) forums and I think at that time there was still the Fishin Alberta Message Board (FAMB) around. Western Fly Fishing had a forum as well as the Fly-angler forum. Alberta Fly-Fishing Forum (AFFF) sprang up in the vacuum caused by FFA shutting down.
So there was plenty of forums around and I think the action was spread a bit thin in most of them. Some of them have since disappeared. During the winter months AFFF was virtually non-existant (as one might expect). There were only a couple of posts every week.
With the addition of the Fly-Fishing section of AO, I don't know if there is a need for AFFF to return.
But if Doc thinks it's worth his time and effort and/or money to keep it afloat, then giv'er
