The server is now live!
Due to the horrendous popularity of MvM at this moment, the server is likely to be pretty busy at all times right now. In the next few days we'll be trying to figure out a better way to get Giant Bomb members into the server more quickly. For now, your best bet is to join the Steam group and gather a few people to hop in. I'll be spreading admin rights around so that we can password the server when need be.
Valve released no documentation whatsoever to server admins when they launched this half-assed mod (it's literally no more than a few custom configs), so this will be a learning process. I got the basics set up tonight, but it's going to be experimental for now.
Input is always welcome.
