Possibly so, Closed Groups are increasingly common on FB and one tends not to have that in mind when you have access, I think George invited me to the groups when I was contemplating the purchase of a Skyfire and before I moved my aspirations up a gear, or several, to the Syil X7.



These links get you to the groups even if not logged into FB so they should at least allow you to see the join request button -
