I developed this book over a couple years a while back. I haven't worked on it in months, but since I have just recently joined this board I figure I may as well post it.
The book has many spelling and grammatical errors, but unfortunately I lost the master file in a computer crash and so I can't really go back and update it without starting from scratch.
However, any feedback would of course be appreciated.
