• Administrator
• user1 = belongs to members group, has no other permissions
• user2 = does not belong to members but has ReadWrite permission on Domain
• user3 = does not belong to members but has ReadWrite permission on Workspaces OR Workspace OR Folder OR File

1. As Administrator, add a comment to the File.
2. As user1, reply to the Administrator's comment on the File.
3. As user2, navigate to the File and click on the link "1 Reply" under the Administrator's comment.
