The web site no longer exists so perhaps the entire post should be removed? It's a sticky, and I assume Bayes doesn't post here any longer.
From the description it seemed like a good site, I guess the owner didn't make any money from it though so closed it down.

I used it all the time before I knew how to use excel.
