Can I submit my articles in HubPages, or should I create an entirely new article for Ezine?

HubPages will penalize the score of your hub if the content is also found elsewhere on the internet (because it is then duplicate content). Content should be unique and high quality so it is better to create a new article for Ezine. However, it does not need to be the same length or quality for Ezine - you can simply tell the basics and then refer the people to your hub article here.

You should create unique articles for each site rather than reusing content.

Yes, that was a question that I had as well... It appears that the consensus is to write another short article for the article submission sites...

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.
