If I send a message to my opponent when I resign the game, will he/she receive it if I just click on the "resign" button; or do I have to make a move and submit it in order for the message to be sent. I ask because the instructions say that your opponent will receive the message when he/she makes the next move. But if I resign there is no next move for my opponent. Does this question make any sense to anyone? Or am I living up to my username.
Your opponent will receive the message. He/she/it can see the message either when they view the game or under "recent messages" in "My Home".
Or if you want to, you can send a message to them by clicking on their profile link and clicking "send message". That message can be viewed without loading the board.
Welcome to the site, by the way.
