1. A game server no longer reports to the GameCQ master server by default. So /gcq command line parameter was added to enable this. This allows it to report to the GameCQ master server IF the master server is online. To determine if the master server is online, use the GameCQ lobby client app.
NOTE: The GameCQ master server is only used by the GameCQ lobby client app. If servers are not reporting to the master server, they will not appear in the lobby client.
