Where can I find the Friends list? How does Steam's Friends system work in CSN?

To invite a friend to your game, follow these quick steps:

1. Open your Steam overlay while in CSN by pressing both [SHIFT] and [TAB] at the same time.
2. Right-click on the friend in your Friends list whom you want to invite to your game room.
3. Select "Invite to game" (above the "Invite to chat"/"Invite to group" options).

If your friend was not in CSN when the invite was sent, accepting the invite will only open CSN for them and take them to the main menu. However, if your friend was already running CSN when the invite was sent, they'll be automatically redirected to the same server, channel, or match as you upon accepting your invitation.

To join a friend that is in a CSN game room, right-click on their name from your Steam friends list and select "Join game".
