Chrss (Chess by RSS) Dashboard widget can be used to keep track of your chess games. It's very easy to use - simply enter your user name and it will show you how many games it's your turn to move in. When someone makes a move in one of your games the number on the widget will change. You can then click on the widget to go straight to your games list on chrss.
