Its mine. All mine !!
Im not old, and I'm certainly not bold. but 4 years ago or so I was told to "get rid" of all training notes and software.. I obeyed.. "I got rid" to my pc, and it remains stored on disc.
I've got a piece of paper( legally) that now says that I own these documents..and there was no objection from the Crown.
It wont take a rocket scientist to reproduce a lot of it. but it will take many thousands of man hours, and who can afford that these days.? Its interesting stuff if nothing else, but the short-sightedness of PMA astounds me.
