I have a link to it on my home page, and have made a point of visiting it and the five sub-sites every day (takes about 30 seconds) - but recently they've all gone as George says.
My wife saw something in a paper about the whole site folding, which would be a shame. Clicking on them always made me feel that if I didn't do anything else worth doing in a day, I'd do that.
If anyone knows anything definite, post it here.And if we have lost it, and there's anything else like it, let us know.
