Why is it necessary for the system to send me a message telling me what I just did? I can understand getting a message when my opponent rejects a double, although I don't get any messages about other game events ("Your opponent rolled double threes!!" or "Your opponent left a blot on his 6 point!"). I suppose it's a vestigial reflex left in the system after the conversion to multi-game matches -- it was easier to leave it in than to program it out.
