I just got a few articles of mine published to Ezine, but now I wish to change my author name on it. There is an option alright .. but will I be able to change the name on the already published article or only on future articles?
I think you are able to change it, previous and future.But better if you can reach Ezine support to get this answered.
Create another author name, delete the original and resubmit the article under the new name - that's the only way I can see. Correct me if I'm wrong, though.
I am not sure about this ... when I tried to delete an article, a message was displayed that said that I would not be able to submit the same article again!
You can change your author name; that will involve changing the name on all the articles too. Or you can create a Pen Name (alternate author) and use it for all articles from this point forward.
