I have finished 2 chapters now. I'm debating whether to post them or not. They won't really do much good if you're trying to learn but it would be good to get some feedback on them. However, I need to work on the rest of the tutorial conversion and write some new chapters, plus general editing, and I don't want to get sidetracked making serious editing in these 2 chapter right now.
So, if you're interested in seeing what I've written so far, post a comment and let me know. Otherwise I'll just keep writing and post everything up when the initial rough draft is complete.
