The Exceed onDemand Users dialog box displays a list of users who have previously logged into Exceed onDemand Server. You can use this dialog box to enable or disable share access for the users listed. Check marks indicate that a user can share your X session. Click the user name to change that user's share status.
When you click OK, those users to whom you have granted access (those with check marks) appears in the share list and may request to share your session. When you receive a request, you can still grant or deny access.
