Thanks for all your help / support / time - it's greatly appreciated and this year as Smokin H says we have had a lot of marshals signed up and out on duty much earlier in practice week, this makes getting all the 12 sectors locked down and signed off easier and means the following session starts on time.
You can do the online course at the TTMA tent but would advise getting it done before travel then you can sign in to a sector where you might have a preference to be stationed.
I'll be at MGP doing Response Car thing again and usually at Paddock / TTMA office/tent 60-90mins before leaving to my start point on the course if anyone needs a chat or help or ask the guys and girls in TTMA office.
