With the book finally out, and people reading it in the ebook form, I am now receiving comments about some of the stuff I missed in editing (mostly formatting). It's true, what they say: you can never do enough editing. Mind you, these books have been in editing for more than five years now, and have been edited by four different individuals.
If you find an error, please keep reading. However, I would appreciate if you note the page number and give my a rough idea of the error you spotted and where it is on the page. I'll go to my master copy and make the edits, and post a revised edition soon.
