find someone to host a server, he just makes a custom game, but when choosing the player mode for each slot, change as many to "network" as you want opponents. if he is behind a dmz or firewall, he needs to open up port 61357 for tcp/ip. then he will have to give everyone else his IP to connect. you connect by using the Join Game button and typing in the IP. on the other hand, if you know how to pass parameters through commandline or shortcuts, to start a server defined by your default (server.ini) use -server. to join use -client xxx.xxx.xxx.xxx
