Content authors are the users who create content for the Formatted Text and Images and Formatted Text and Images (Secured) parts on your website. In Users & security, you can select whether these users also have rights to manage workflow tasks. For information about these task rights, see Approval and Workflow Task Rights.
When a content author completes the design of a part, he submits it for approval by users in the Content Approval role. If the Content Author has rights to manage workflows, he can select whether to submit it to the users in the Content Approval role associated with the default workflow or those associated with another workflow.
