Sorry Ewan, Karoline is spot on with her posts above. There is not a cat-in-hells chance I would even think of responding to an enquiry like this from Mr Roski or any other major event organiser without a detailed set of proposals with EVERY last I dotted and T crossed.
I believe Im correct in saying that in the USA Mr Roski has stated that he does not recognise the RFL (The US equivalent of the FRA) If this were to become the case here in the UK then who would represent the interests of the roboteering community in any possible future negotiations?
Just something to think about!
