My guess there are several reasons people go missing. We have had some deaths amongst the players here. Some leave and go play elsewhere for a host of different reasons. Others just get bored playing the games and find more constructive things to do with their time. Myself, I still play as a pawn and play games on facebook but have found other important ventures to direct my time and talents. Still like playing games but devoting more time to family and church and other constructive areas of my life.
