Hi Simon,
First off, let me just say I'm not knocking you in any way, it's good you've sat down, thought about it and done something
Anyway:
2b. - OK, but requires some consistency maybe?
2i. - Not needed then IMHO. I'd only make a rule if you have to - E.G. batteries must be connected with connectors.
2j. - You missed that one
6. - If there's ever to be a big meeting the names will have to be right
11. - Doesn't make them right.

It is worth looking at 10th electric rules too as these are really just bigger versions aren't they?
11q. - But someone turning up without a buzzer will be turned away? It just seems a really odd idea to me. Imagine them sat waiting for the start all 'buzzing'
11r. - Ah ok, makes more sense. But could be fairly hard to police?
