Hence my disclaimer at the end
I am building the website primarily for myself. I have posted this message on the off-chance that there are others like me who also see value in a novel learning assistant.
Chord charts and self-help books already exist for other instruments. Basic chord charts and self-help books exist for the PSG. There are several PSG computer programs in existence. There is an obvious demand for these things.
We all know that the PSG - even with a "standard" copedant and tuning - is tricky enough for newcomers to get their head around. Here in the UK we are lucky enough to have some great players who also offer up their valuable time to help others. That is fantastic and long may it continue through the generations. It is - in my opinion - the best way to pass on knowledge.
No software will ever replace the human touch. And I say that as a "PC nerd".
