Here’s a quick summary of each role, with detailed descriptions further down this page:

• Administrator: The highest level of permission. Admins have the power to access almost everything.
• Editor: Has access to all posts, pages, comments, categories, and tags, and can upload media.
• Author: Can write, upload media, edit, and publish their own posts.
• Contributor: Has no publishing or uploading capability but can write and edit their own posts until they are published.
• Viewer: Viewers can read and comment on posts and pages on private sites.
• Subscriber: People who subscribe to your site’s updates.

Each user role is capable of everything that a less powerful role is capable of. In other words, Editors can do everything Authors can do, Authors can do everything Contributors can do, and so on.

Most Creators will begin as a Contributor, just until they show us they handle the role of Author.

We are happy to Add the right candidates to the Editor role for the site over time.
