I have a game that I am trying to set up that needs one more player.
I am also an active participant in a game. There is another player in that game who I find it to be congenial to engage in diplomatic exchanges, even though we are playing countries where our opportunities to work together are limited in the early stages of the game. He has commented that it is too bad I was not playing one of the countries on his side of the map, because we could form an effective alliance.
My question is whether it would be a violation of the letter or spirit of the rules to extend an invitation to him to join the pending game? Were he to accept, we would not have any pre-existing plan to work together. We would not even have an idea of what countries we would get. On the other hand, we would obviously both have an expectation of a high likelihood of working together. (Or else he is BSing me).
Also, if it would be okay, through what mechanism? Can I send him a PM while we are engaged in a game?
