I'm always grateful for feedback on almost anything you care to address about the book. If you have a better way to explain a certain topic and would like to share it, great. If you think a topic in this book is unclear, I would like to know about it. It's always helpful if you can pinpoint the problems, and suggested cures are always welcomed. If you like the way a topic was handled, it's always nice to read good comments, too.
If you find an error or typo in the book, please let me know as soon as possible, including the page number and line number.
