Sorry Ron... the changes are very minor now...spelling, punctuation and appearance.
I would stop reading it if I were you.
If I am going to do true additions. They will be new paragraphs on tuning and mods. or function and theory.
What I am doing is just bringing it to the top of the page when it drops off the bottom.
Because there are lurkers and new readers who don't know its back there 2 pages.
And they might not ask... but they might read.
