Private first-drafts
Until you’ve submitted your first draft for editing, no one other than you (and any collaborators you have) may see it.
Until an assignment has been submitted for the first time by its collaborator(s), it is in “first draft” stage and can’t be viewed by non-collaborators. Once the assignment has been submitted, users will be able to see when the first drafts of the assignment by visiting the revision history.
If an editor wants to have access to a collaborator’s first draft, they may add themselves as a collaborator on the assignment.
