Scourge of War Boards

I think the automatic responses of AI subordinates can be turned off, but I don't remember how...
The messages are instantly created every time a regiment receives an individual command, not when I order the whole brigade.
I'm playing multiplayer. In MP options I have courier messages at level Brigade or above.

While in game hit the menu button and then options. It is under the general options.

NY Cav is right, but it doesn't work when playing courier by brigade. I've played in several of the Hits and Couriers games and always have them turned off, yet I too get the courier return spam.

But playing in GCM games with courier responses turned off, I only get player sent couriers.
