The documentation problem is entirely my fault. I managed to stay up to date through version 8.0, but then so many things happened so quickly that I got swamped. Then I got depressed and gave up.

Also I made the mistake of writing the manual in MS Word. At the time, I couldn't find a standard way to insert pictures into a TeX document, or I would have used that. (Now, of course, there is a standard way.) There is an effort underway to convert the manual into a web-based format in a git repo that anyone can contribute to, but that effort is 90% done and you know what that means! :)
