nabla: And just as a side note on the subject. If the time comes that Fencer does change the rating system, in the past what he had done when a change happened in the rating system was run every single game already played on the site through the rating system to get a new accurate rating..... so if he were to do it again, there is a chance that current games / matches be ran through to get the new rating.
So just a thought to keep in the back of your mind - even though it does not matter to the current rating system, if he were to make the change - there is a chance your current games would be taking into account for the future rating change.
Not that I know if he plans to do it or not - but I have always agreed that it would be nice if different games used different ratings systems... instead of all games be lumped under the Chess rating system which I think he uses.
