Walter Montego: I think it's too complicated.

Why not when the last person makes their move, the next move starts and the clock resets. You would still have a day (or 2 or 3 depending on the limit) to make your next move. I don't really get the problem. In this case I would perhaps not count weekends as with other games, so if the pond started on a friday the move wouldn't schedule to end until Monday (unless of course everyone moves!!)
