In my experience two accounts do seem to be necessary and you have to wait a while (sometimes hours or overnight) for results to appear. Other times they appear quicker. I actually tested with 3 accounts but I doubt the third made any difference.
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.
