I have completed the PDF, Kindle (.mobi), and Nook (ePub) versions of the new edition of the Tech study guide. If you’d be interested in having an advance look at it, e-mail me, and I’ll send you a copy.
I have an ulterior motive, of course. I’d like to get your comments and see if you can find any typos before I release it to the general public. I’m only going to send it to about a dozen people, so that I can keep track of the copies that I do send out.
