Just Mark, now!
When I registered for this fantastic brotherhood back in the day (on the other board), I couldn't think of a handle. I was watching the Sox game and dreaming of my favorite city, Boston, and picked BostonMark. Little did I know that the massholes would rise and I would be asked literally every day where in Boston I am from
So here I am, just Mark. Hope that works for you all!
