I know that a previous suggestion lapsed because of lack of interest but I think it is about time to raise it again.
The problem is that the new tournament has flooded my email with move notifications. Now I appreciate the notice, but one for every game where it is my move is getting too many.
If a new move is made in a game and the player has received a previous email in the last 2 days and not visited the site to reply then a further notice could be warranted.
Alternatively having sent a notice no further notices should be sent even, if another game move is required, until the recipient logs in, whether he plays or not.
Lets try to save the planet and save some unneeded email traffic.
