When should we considere removing a hub from Hub Pages so we can use it elsewhere?

No srossjul you can't use them on articlebase, ezine or any other place. A hub is unique and can't be copied even though its your very own. You could rather un-publish it or tweak the original and create a whole new article to publish on other sites.

As far as I'm aware, you certainly un-publish your hub and put it elsewhere. You also need to be aware of the rules where you're planning to put it. Check the terms and conditions of the site it's going to, because some writing sites only allow content that has never been on the internet before (even though you may have deleted it from Hubpages).

You may want to start by writing about 10 completely new articles and putting them on another site - have 2 (or more! ) sites going at once, until you see which one gives you better long-term traffic. I personally haven't moved my articles after putting them on Hubpages.

But I don't see why you couldn't, so long as you unpublish on Hubpages first, AND check that the new site will accept articles that have been on the internet previously.

If I am not wrong, we can't remove our hubs from Hubpages once published. Though if you feel like you may re-write them over again and post anywhere you wish. If there's more to this, it would be news for me too!

Are you allowed to post them on ezine articles if they've been published here.

Tell me more. Do you mean my Hubs can't go on ArticleBase or Squidoo while active here? Tell me more!

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.
