At a technical level, stories may be posted by any authenticated user (someone who has registered on the site). By default, the story will be unpublished so that a site editor can review and make the final determination about publishing. A rule will also notify the administrative email account for the site that a story is pending review.
The location field provides the linkage between this story and a location already created on the site. This story has been promoted so it appears on the home page.
This post can be edited to create your own story or deleted altogether.
