Sounds like people are discussing something similar to Star Wars: Fanworks
(which was created for audio drama producers). Not so much an organization, as I understand it--could be wrong, as a central place for promotion, sharing info, and things like that. I don't see why something like that, instead of an association/organization, handle ST FF and FA wouldn't be a better fit.
Just my 2-cents. That and $4 will get you a coffee.
