AbigailII: I thought about that but there isn't really enough information in the RSS feed to make the decisions. Besides, how many rules would I have to write to do this? Email and tagged games still make the most sense me.

Fencer, any thoughts?

MadMonkey: That's okay...but the crux of my request is that I want to know when my opponent has moved without having already thought to go to the site to check it out.

I would get use out of a feature that would send you an email with a game link whenever an opponent moves in a particular game.  There could be a check box near each game board (or something) to indicate that you want notifications for this particular game.

This feature would be very useful for several reasons and you would like to know as soon as possible when you opponent makes a move:

1) When you have a game that is running low on time
2) If you a playing a particularly interesting game.
3) If others in a tournament are waiting for the game to complete.

Thoughts?
