Hi David, and I hope it has been helpful - it certainly was for me when I did it! I changed a couple of minor things such as the firmware version etc. and a couple of typos I came across but nothing to merit a revision. I did make some changes, again minor, to the Numbers version, which I tend to use now since I have made the switch over to a Mac and don't use Excel much any more.
I can email my latest version if you like, but as I say there really isn't a lot that has been changed.
When words become unclear, I shall focus with photographs. When images become inadequate, I shall be content with silence. - Ansel Adams
