I'm in the editing phase of the newest edition. I hope to release it within the next few months. If anyone wants to help out by editing, or even just proof-reading, the book, please let me know.
Since I self-publish these books, all editing is done by volunteers. If I paid for it, it would cost nearly $1,500, which is more than I make in sales per year. Not complaining, just letting everyone know why it can take so long to write and edit it.
