Steam group for the correction of this error

Hey all, i'm playing Empire Total War with Steam, and when i try to host a game for a buddy and me, i often get this error "Failed to join game: No response from host", and we can't play. Usually when my buddy try to host for us, he get this error too. And we can play together only if we find someone with a host that allow both of us to join it. It does that for Empire, but i guess it is for Steam in general, not sure.
If you have this error, or have some interresting comments about it, i invite you to join this public group to show to world (Steam and who else?) that we are very annoyed by this fact.
All members have the rights for writing announcements and comments, so don't hesitate to come and write.
I draw one's inspiration from the Steam group ETW Multiplayer Campaign and Empire: TW - Multiplayer Campaign Connection who militate for the creation of an update that allow multiplayer Campaign for the Empire game.
