I found many hubs containing links to other hubs with their referral inside it?

You can use the referral tracker in your Hubs and your profile and receive full credit. There is a suggestion that may change in the future, but right now it works.

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.
