The Content Manager role, not only inherits all capabilities of the Editor role, but also has the capability to manage jobs on your account; that is: 

• Upload new jobs from all available media sources using the +-sign widget
• Archive or delete jobs in your HOME page using the x button to the right of the jobs

Content Manager Capabilities

Files uploaded by content managers are still subject for approval if the profile used has a designated approver.

If your account has FILE SHARING enabled, you will be prompted if you want to share access to the guest editor during upload.

NOTE: You can invite up to 10 guest editors on a job.
