I've been lax in mentioning NotN lately.
I took a week off to help Alex with his release of Getting Home, which by the way looks to be doing pretty well - congrats Alex. If you haven't picked it up, you should do so now. It'll only be 99 cents for another day or so.
Anyway, I've also spent several days researching material for the book and consulted several folks you know - not as experts per se, but just as someone to help me logically walk through some scenarios.
I've also had several things that have needed attending to and have thus focused my efforts elsewhere.
So this is the long way of me saying that I'm about halfway through Chapter 2, but I like where I'm headed, so far. Maybe when I finish Chapter 4 or 5, I can start releasing some chapters here on the blog. Until then, I'll be in and out of here - mostly out.
