I agree a committee is the first priority
Voluntary basis is fine for the first year, but if it is a success - breaks even or makes a profit, then the organisers should have an honorarium, or at least expenses paid. I'm happy to help on that side.
Lilian/Robert - what is the problem with the pig classes at RHS please. I'll contact David for you if you like? I can also ask him about organisation of paperwork in general.
