Using Triond articles for Expert Columns and other sites

Triond only accepts original content, which you can then post on other sites with the same user name. Helium used to accept duplicate content, but now requires original content. Also, you must agree not to republish the content anywhere else for a year after writitng. Once the year has passed, you can republish it, but as the previous responder says, it's not really a good idea, as it can interfere with rankings.

When you sign up for Expert columns they will send you emails with questions. The questions will ask you for links to your previous articles if you want to re-post. They will only allow you to re-post if the username is the same. Although, there is a chance that your account will be rejected. Don't worry, Triond won't kick you out as i am re-posting my articles without any problem. As for Yahoo Voices and Helium, i am not sure.

I don't understand what you mean by mirrored articles. All I know is that Triond will only accept articles that are original and have not been published anywhere else on the Internet even if they were written by you and you own copyright over the articles. They only accept original and unique content. ExpertsColumn on the other hand will accept republication of your articles from other websites as long as you inform the admin that you also write for those websites. It's best if you use the same username so that there is no doubt that the articles belong to you.

Typically, only Triond accepts mirrored articles. I know expert columns and yahoo voices do not accept mirrored articles because they want their work to be original and unique to their site. Who would pay for articles they could find on five other sites.
