G3 Hemi Swap group on Facebook.
And remember...joining a fb page or group doesnt mean you have to 'friend' everyone you meet...which means you can maintain a high degree of privacy...
You also dont have to use your own name.
My employment prevents me from actively participating in the 'social' aspects of fb....so I use a pseudonym...those who know me in real life know its me...but casual observers just see my 'alter ego'....no job, education or family details listed.
