There are three levels of access to every script. Collaborators (with the role of Owner, Admin, or Editor) have the ability to edit the content of the script. Collaborators with the role of View can only add comments (visible to other collaborators).

The third level of access is for external users (not a collaborator within the project). Like collaborators with "view" access, they can only add comments. But unlike project collaborators, they cannot see other parts of the project. They can only see the script reader page. Additionally, their comments are only visible to project Owners and Admin.
