Perhaps one can remain on the chart if he has been playing it or has finished a game, instead of just basing it on finishing a game. Require a certain amount of movement or finshed games per quarter. But even taking the scenario of a game that takes 4 months to finish with the players moving everyday, I think three months is more than adequate. You should have more that just one game going to retain a spot on the chart. Just ekeing out the bare minimum might be enough by the rules, but it sure isn't by the spirit of it. The rankings should be for active players, not people that play one game every six months. I'd go with delisting them until they played regularly. As an option there could be a link that would list all members ratings in an inactive chart of some sort, where a column on that chart could also list the player's last move in the game so rated. In fact, such a dated last move would be a welcome addition to the charts that we have now. How about it fencer, could you put the last time a person moved in the type of game in question on the game ranking page? Just having it public would show who desrves their top ratings. Anybody that sees a top rated player that hasn't moved in the game type of interest in over a year would know at a glance where not to look for a game to play. If you do make it so inactive players are delisted until they play again, it would also alert someone that they might want to get some games going before that happens.
