I got MNC for PC for myself and six other friends for Christmas, and learned to my dismay that there's no automated matchmaking system. We tried the dedicated servers thing a few times, with Team Fortress 2. We had so much trouble finding servers with available slots for everyone, balanced teams, decent ping and non-retarded modes and options that it put us off the game. Could you please, please add in a friendly way to access your game? Something like League of Legends' system or the Xbox LIVE system would be great for us.
Just host a game of your own and invite your friends, as of now the server browser is very limited, but you should be able to get all 6 of your people in with you. When the game is fully released (outside of Beta) there should be a kick function, so you can just kick people to make room.
