I've been running the site www.yourlotteryresults.co.uk for a year now. The most popular section is the syndicate reports which show a syndicates winnings, etc, since the National Lottery began over 10 years ago.
The site has always been free but I've just written a system to charge automatically for a years subscription. Its only £3 a year, but most of that (after the processing fees) is going to Children's Brain Tumour Research and Paediatric Neurosurgery Wards in Nottingham.
