I post links from Yahoo that solve or give answer to asker's question many times, since Yahoo provides these help links there is nothing wrong in posting them to help the asker see information is valid and not some scam..
If the link has nothing to do with enhancing the answer, then it is a violation no matter how many times you do it. If it just goes to a personal blog ot Facebook page, that is a violation.
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.
