fismoluni: The suggestion you make about a player only needing to be playing a game to remain in the ratings has been made before. The problem is that a game, on a turn based site such as this, might take a long time. I have had one game which went for about 2 years and the move number was up in the 70s or 80s. With up to 30 days per move and games which can last many moves, this is going to be a recurring issue.
