Andrew, I certainly will! Actually, I already have!
Facebook doesn’t provide the search and organizational features of a forum. Spec Racer Ford and Spec Miata have both. Facebook becomes more of a show and tell of accomplishments (e.g. 'look at my new <car|paint|clutch|etc.>) while the forum is where more technical issues are discussed (e.g., on Spec Miata, my car was hit in the front fender, does the chassis need to be replaced (the answer was yes)).
I have lots of questions. Have drivers installed dead pedals? What seat do they use? What data acquisition do they use? Have any of the front runners at NJMP posted videos with data acquisition, especially throttle position?
I also have NASA mixed class driving questions, some specific to what driver’s did in posted videos.
I just don’t see how those become a discussion when Facebook pushes the topic down as more topics are added.
