An administrator has full and complete ownership of a blog, and can do absolutely everything. This person has complete power over posts/pages, comments, settings, theme choice, import, users – the whole shebang. Nothing is off-limits, including deleting the entire blog.
Only one administrator per blog is recommended!
As an Administrator of a blog, you can change other users’ roles by following the steps below.
An editor can view, edit, publish, and delete any posts/pages, moderate comments, manage categories, manage tags, manage links and upload files/images.
An author can edit, publish and delete their posts, as well as upload files/images. Authors do not have access to modify, add, delete, or publish pages.
A contributor can edit their posts but cannot publish them. When a contributor creates a post, it will need to be submitted to an administrator for review. Once a contributor’s post is approved by an administrator and published, however, it may no longer be edited by the contributor.
A contributor does not have the ability to upload files/images.
