Many thanks for all your offers. I have now got a couple of knowledge-able types coming over and we'll have a go at connecting up all the bits. May well take you up on your offers at a later time if that's ok.

Hope all are well and avoiding the showers, I got caught in a massive downpour just as I decided to get in the car. Me, the chair and the door/inside car are still damp!
