It would be interesting to know how many accounts have been inactive for a year or more.
I think that an active player is one that has played at least one game in the last 12 months. I can confirm (or deny) that in about three weeks when it will have been over a year since I played my last blitz game. Then it's a simple matter of subtracting the number of active players from the total membership.
It would also be interesting to know why your hair is on fire in that avatar pic, BISHOP?
