More ref's are a great idea, I will put my cap in the ring if you need more helpers.
I think also we need to start running more visable numbers on the cars, not cut down or hidden etc. Yes I know we all know what each others cars look like but during racing and qualifying its difficult to tell if the car behind you is lapping or racing you. That way when the race order is called out after a minute or so you know where you are and exactly what car you are chasing and what car is chasing you. Hope that makes sense...
