Carl - that's great news about your local Banded Demoiselles!
That's a great idea about emailing...I also saw, when I was doing a bit of nosing around on the BRC website, that they've got a brilliant page that lists (with really useful links), all the other organsations doing surveys...plants, mammals, frogs, reptiles etc...What a great resource!

I'm going to be surfing all those websites for hours....well, I would be if I didn't have to go and do some work now
