Can I publish my articles here?

Yes you can because they are your own articles.

Relache The articles are stilled cached by Bing and Yahoo, (but not Google). No, they have not been copied by any writers so far. Thanks for answering my question.

If the articles are still cached by search engines, your content will be flagged as duplicate. If someone copied them and you don't know about the copies, by pulling down your work, their versions have now become the "originals" and you'll be flagged as having duplicate work plus it's really hard to then prove ownership and get the stolen material taken down.

But if neither of those situations are in play, you should be able to use your material on this site.

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.
