"I get all my games from tournaments. When I first joined I used the open invites mainly, did have my challnege settings open for a month or two but soon got fed up of every Tom, Dick and Harry and their dogs sending me challenges without a message, usually with 1 day timeouts and them as white."
...why not adjust your minimum timeout under your challenge settings? Alternately, what's wrong with simply deleting the game if it doesn't suit your needs or playstyle?
I'm not trying to call you out - I just don't understand why some people profess to require a message prior to a challenge. When someone challenges me, my first thought is usually something akin to, "Yay! I have another game!"
