I don't understand how to put a limk in my hub, it keeps telling me to use only letters and numbers?

I'm sorry you're having trouble with this. It's pretty easy. Here's a link to the learning center on how to add links to your hub.

I have not figured out how to do that myself. If I figure it out I will let you know.

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.
