How can one collaborate on a data management plan?

First, all participants must have an RDMO account. Then, one of the team members (the owner) must set up the project. The owner can then add additional group members. The owner needs either the email address or username of each group member.
The owner can assign a status to each group member. Guests can read the DMP but cannot edit it or change the settings. Authors can write new text and edit responses. Users with manager status have nearly the same permissions as the project owner. They can create snapshots, modify project information, and so on, but they cannot delete the project.
