Do you mean "Started"? You need help with getting the online portion started? If so that is real easy. Go into any game mode and choose to play in a public room. There is a series of options when you choose your game on the left hand side of the screen. Check them all out. If you do that you can't miss it. To see if any of your friends are online just go to the option of "Playstation Network" or what ever it is on the list.

We’ve also seen a few questions about the Brink statistics website and what you should be doing with the VIP code that’s displayed in the game. When the Brink statistics site launches on www.BrinkTheGame.com, you’ll be able to register a profile on there and can then use the VIP code from inside the game to link your Xbox 360 gamertag/PSN ID/Steam ID to it. More details on all of that soon!
