There actually is an official FRA Facebook group - I think it is called The Fell Runners Association, or something similar. It is very rarely used, and only for official statements.
Interestingly in a recent debate on that page, a prominent person in one of the regional associations described a senior FRA committee member as a "prick" (that word keeps coming back!)
The facebook page which we generally all refer to is Fell Runners UK and is indeed not officially tied to the FRA...
I think the fact that new members do still pop up on here asking questions, shows that the forum is worthwhile… there may be less of a response than the facebook page, but the info on here is generally worth listening to (quality not quantity!)
