I remember reading that Facebook up until only recently, was not safeguarding your privacy to only specified friend groups. That said, I'm still not yet confident that this has really been fixed & resolved, so remain undecided whether to participate or not, so my apologies go out to all Synthzone friends & members who have attempted to invite me to become their Facebook friend. Another concern I have with Facebook is them sharing your personal data with advertisers & web tracking companies . - Scott
