Well it's kind of a manual afair, 1 of you sets up a came (host online game) then goto sriends on the bar at the bottom in the race lobby, you then send a specific frend or friends a message, in this let them know the track and car oyu've set the race up to use. Then your friends simplt goto online race, join race and stick in the search filter the track and car that your using. When they pull up the list of available races they should see your name as the race host.....It's converluted but easy to do (though it sounds longwinded) With the problems online at the moment it may be best for the host to use "private" slots making it a private game, this will keep things stable. If your stuck shout up again.
