I tried LATEX sometime in the past, but I found it too feature rich and complicated for occasional use. By the time I wanted to use it a second time I had forgotten a lot and had to relearn. Right now, if I need to rewrite equations or formulas from scratch, I'm using Open Office, it has a decent formula editor and it's free. I don't know HTML, but I've heard that it's not very good for writing equations and formulas, and judging from some of the renditions I see on the WEB I suspect it is true.
I have a little more work to do on the chapter 2 errata, just the last 2 or 3 pages. As soon as that is done I'll upload it and hopefully some of you will give me some input. If there is interest, I'll also upload the corrected pages for chapter 2. That's going to take a little longer because although I've got most chapter 2 pages done, it takes quite a while to do just one page of the few I got left.
