Because I'll be out this night, I'll set it up on an automatic schedule. The sessions should turn over automatically at the usual times - Practice, Qualifying (10 mins), Race 1, Warmup (10 mins), Race 2.
There will be no need to leave the server, as it won't be reset between races. There won't be any ballast change between races 1 and 2, and there won't be any reversed grid positions.
The admin password will be the usual race password, if anyone needs to become an admin to kick the session over to the next one (shouldn't have to).
I'll be able to work out results from the server logs, but I'll need someone to post up the replays if you want me to check for penalties.
