Thanks for your warm words. And yes, there are now DOZENS of books about Hypercard, each one of them an improvement over Apple's meager manual.
The best book for beginners is the oldest one on the shelves, Danny Goodman's HyperCard Handbook (See Vol 3 John 27).
I thought your financial stacks have quite a bit of potential. I will probably release them some time in the future as part of a Mr. Wizard project!
