Part 1 of Chapter 3 has now been uploaded to http://exploreib.wordpress.com

So far, I've only had comments from five or six people, so I'm beginning to wonder if it is worth finishing this job :-) There have been over 400 views of the pages, so either I'm doing something incredibly well, or so badly that no one wants to say so!

Part 2 of Chapter 3 will follow in due course, but there may be a wait after that as Chapter 4 is not yet finished.
