The site settings page is wrong, it sais:
Receive email move notifications for your opponents' moves?
If you turn notifications off you will need to visit 'Red Hot Pawn' to check on the status of your games.
Other 'Red Hot Pawn' users will only be able to challenge you when you have fewer than this number of active games.
You will still be able to initiate games yourself above this limit.
This last lines (under the notifications setting) are on the wrong place!
