At the end of the current F1800 season, we'll be moving on from netKar and onto Assetto Corsa on Tuesday nights, now that AC multiplayer is available. It's the logical progression. It might be a while until it's mature enough to have a full-fledged season. We might have a number of trial races in a variety of cars to get everyone used to it. We'll have to play that by ear as the game progresses.
If anyone's unaware, we've already been having trial races in AC on Thursday nights, and will continue to do so until this netKar season is finished. Check out the Assetto Corsa sub-forum for details.
