Author
Creates and edits pages, uploads images and sends a draft to review. Cannot publish.
The editorial team
Each editor holds one or more roles. What a role may do is a checkbox per capability, which an admin changes in the CMS without a deploy.

Roles
The defaults the CMS starts with.
Notices
When a page goes into review, reviewers get a notice. When it is approved, approvers do, and when it is rejected, every author gets the note. The person who made the move gets none.
