mctrivia: What you say may well be true, but I like the idea of having some type of speed rating or average. The amount of games a player has going at one time is not a consistant indicator of how often they make a move in a game. A speed rating would at least give you an indication of how often they move if it is something that is important to you that your opponent moves regularly in a game with you. People that move at a slower speed than a person wants to play at would be avoided in this manner. The slow person loses nothing when their opponent moves fast, but the fast person does if they want the game to progress everyday day or so.
As for the "clearing your games each day" bonus that pgt thought up, this would incourage those interested in the action points to move at least once in each game that day to get the bonus points. One move a day is a pretty good pace on a turn based site and I think the idea warrants looking into.
