When an author shows promise (and I trust you) you will become an 'Editor'.
As an 'Editors' you can post and edit any (not just your own) content item from the site. You can also edit content that has not yet been published. Editors will see unpublished articles in the section indexes and can select for editing, where as an Author or Public (unregistered) user will not even see the unpublished items in the list. However, 'Editor' users cannot, publish or change the publishing status of any articles, even their own.
