Ban anyone with a certain percentage of games waiting to be played, from posting on any message boards....

It would force some people, who are unable to use personal control, to limit their amount of started games to how many they can actually play :)

I do understand that many people prefer, and don't get frustrated with longer games. If someone really wants to only make one move every 10 days or one a month, and that is okay with their opponent, thats fine. Just inform your opponent that that is the case, so they know. Put it in your profile... I have many games and will most likely use the whole time limit for every move.
It is the person whoslow plays for pleasure in others frustration that fires me up!
