Hey guys I need a little help making my own server/ room can anyody help me?

is there some video tutorial, that is really confusing

multiplayer > start new game > select ur settings > done.

I assume you've get to the create server window and it still doesn't work so I assume you might want to check if your port 63392 is open.

this site might help you out: http://portforward.com/routers.htm

It'll help you out to open your port in case you don't know where to start. They even got an application that will check if your port is now open and another one to open the ports itself depending on the game you choose.

Have Fun !
