Welcome to the new Pro Hosting community!
Modern Warfare 2 Pro Hosting was established for players wanting to find scrims, ringers and tryouts. We know how hard it is to go into IRC Channels and find the things you need, and then have to add the players steam and do a bunch of pesky work. Our goal is to bring that kind of service to Steam! We recommend all players to use the Steam Group Chat Room and use the chat room as a, what some may call it, the Steam integrated IRC channel. If we can get all members of Modern Warfare 2 Pro Hosting to idle the chat room, as they do the IRC channels, players will simply have to just post in the chat room what they need, another member will respond, and then simply click on their name and click invite! Easy, simple, fast.
