Project roles are necessary to establish user access (see What are Roles),

To create a new role for your project:

1. Navigate to Permissions.
2. Click Create Role . 
3. Select the type of role you'd like to create:
   • Review - Reviewers are users to be invited to view your project materials after the project is launched
   • Manage - Limited management capabilities as defined by project admin
   • Project Admin - Full management capabilities
4. Customize the new role by using the guided setup to establish role details, permissions, download options, and additional access if desired. See the Download Options and Permissions articles for additional clarification of these features.

Duplicating an existing role creates a new role with no members assigned, but with permissions matching the original role.

To duplicate (copy) a role:

1. Navigate to Permissions.
2. Within the Roles pane, click the options menu (3 vertical dots) associated with the role you would like to duplicate.
3. Click Duplicate.

The duplicated role now appears titled in the format: Duplicated role name (copy).The duplicated role can be renamed using the steps above, then by selecting the Edit Role option from the options menu (instead of Duplicate).
