Using Texmaker, I want to lock the PDF file created so others cannot copy text or print the file?

It wouldn't be effective anyway. There are bits in the pdf format that purport to forbid the user from doing this, but they are really just suggestions that the reader application may or may not act on. There is nothing to stop a user from removing the code that inspects the bits from a free/libre PDF reader, or just to run a tool over the file to remove the restrictions.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
