You should get permission from the original author (usually listed in the history of the article page or at the bottom). Getting permission helps as the author may allow you to post the story on the article itself (posting it without their permission will result in it being removed and a warning/temporary ban).

That being said, there are some stories where finding the original author might be difficult, you can always try messaging an admin to help you search or ask for their opinion.
