Remarks

Notifies Battle.net that the client has joined a game. This is what causes you to receive "Your friend entered a game called _." from Battle.net if you are mutual friends with this client.

SID_LEAVECHAT (0x10) does not need to be sent after this, since this does what LEAVECHAT does but with an added notification.
