WellyWales: Unlike the others I think that it is an excellent proposal. It is very different from controlling one's game number by oneself. It would be much easier if the system could reject automatically challenges, or kick the person out of a tournament when it starts (who can know at subscrition time how many games he will have at the time when a tournament will start?). I think this is the way it works for pawns, so very little more to implement.

Actually, I would have become a paying member much sooner if I could have set a limit on my number of games.
