Hello, I want to make a small indie film (ultra low budget) about how horrible war is with a couple of friends. We are currently in pre-production, and one of our largest problems is to train ourselves with teamwork. Right now, I have the FFUR 2007 mod ready, and my friends have copies of Flashpoint 1.96 (so do I). I want to know that if I made a game, can my friends just put in the IP Address and join? If anybody can inform me quickly, then thank you.

Thanks!
