Can Hubs be posted on other sites, after posted on Hub Pages?

No, you can reword them, or provide links to them, but you can't post it word for word.

Absolutely not. You can unpublish your hub - put it somewhere else, and delete it from here if you wish.

1. Yes you can.2. BUT it will drop your article value a lot.So, do some spinning (not too much) and avoid copy-paste even though you are the original writer.

This is because no one like duplicate content :).

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.
