user153: When playing rated online correspondence chess, it's quite possible that the players' ratings change during the game. When the game is over, which rating will be used for rating adjustments? The ratings they had before the game began, or the rating at the end of the game?

user3270: Every site that I have seen uses the rating at the end of the game.

user19861: Online sites use the rating at the beginning of the game. You can tell that because that's the rating they display even if it's changed.
