Editorial Deadlines is designed to be a list of dates for tasks that need to be completed. These tasks do not have staff assigned. They are just things to be done. The tasks may show in the checklist (if the site is using the checklist).
When clicking on the next tab Editorial Deadlines, you will be taken to this screen:
Label your Next Action from the drop down menu, mark when it is Due, Assign an existing member of your team, or select a new one by clicking on Free text next to the field, to go back to the team list click on Staff.
Set the dates for different phases and check the complete boxes when the tasks are Complete.
Choose the date on the calendar for Target Contract Date, Target Publishing Date, Contract Sent, and tick the boxes if the tasks are completed: Reviews Returned, Feedback Given, Contract Returned, Budget Created, and if it is Approved.
At the end you can add an additional note in the Comment filed.
Click the Update tab when finished.
