Yeah, I hope the full release is this week sometime. You can run the RC in the MP lobbies ingame, though you can't run a dedi server with the RC. When it's released, we have to update the servers to reflect the new content.
@GeekyDeaks Don't worry about it, I would never expect you to punt me off on purpose! It was a bit of a WTF moment though! It did knacker my suspension and aero and thus I had to spend 2 minutes in the pits. At that point I was back to hotlapping and figured I would be better off going to be bed(early shifts alas). Otherwise I would have stuck around for race 2!
