BH, although an update would be nice, I think this is simply a case of life getting in the way of other things. The funds have been raised and I'm sure they're going to good use. That's the important thing and the draw is secondary. With chaps like Iain and Neil behind it you know you are not going to be let down and it's in safe hands.
As for the iPad for the brother, I did chuckle when I read that but then thought about it a bit more. When someone in the family is ill or in need of special care it has a monstrous effect on other family members, whether it's those who provide or work to support and pay for the care or those that perhaps lose out on regular, everyday family life and attention due to the focus being elsewhere. It's wonderful that the brother has received something out of this and I hope it has helped in even a small way.
Without knowing the details I think it would be best to just sit back and know you've helped make a difference to a family and you're a better person for it. The draw will happen in due course. After all, we all are providing the prizes and they're not going anywhere. I particularly want to win your Tomart price guide!
