MGM..wow, that brought me back a few years.
Yes, I was a member..They started calling it GATE because of dumbass political correctness a few years later.
I joined but I realized I was the dumbest guy in Mensa...got tired of the taunting and teasing stuff like "Check out the dumb guy he can only recite Pi to 24 places"
Really I figured it better to be a giant among the little people.
