One issue with Hamachi: the free version appears to be limited to just 16 total users. We have an 18 player game, so would two players still be able to access the network, even if they are not using Hamachi?
I'll be setting up the new forum this week--sorry I have not had a chance to do so sooner.
I've settled on a name: "Chaos and Civility" I think it will reflect the nature of our game, which will be populated by leaders of mixed motives (some chaotic and aggressive, others civilized and diplomatic).
