No there isn’t. There are over 5,700 pieces on the site at the moment, and I am adding to it daily, so it will be a very long list.
I am no computer wizard, so wouldn’t know how to go about providing this. The only thing I can suggest at the moment is for you to click on each of the “JohnF’s Page Categories” items on the right-hand side of each page, where you will get a list by title of everything in that category, and Save each page from your browser.
When I started the site with a different host and different software, the only option was for me to manually create all the indexes. This was prone to errors, bad links, etc. all of my own doing. And was very time consuming.
A quick search of WordPress plugins doesn’t show any reliable solution to this, and what is there would only be available for me as Admin to run, not you as a User.
