To demonstrate how user and group application permissions work, make sure your user is in both Default and Admin groups, leave Administration checked, and check only System Information. Any app you grant access to will not show up until you do any one other thing. This is because the menu list is built before the admin apps runs to save the changes. System Information does not have a menu icon. It's only accessible through the admin app. Now go into User Groups and edit the Admin group. Select Messenger. Now edit the Default group. you will notice the Messenger icon in your menu now. Give the default group access to Addressbook, Calendar, Notify Window, Preferences, User Manual, E-Mail, filemanager, and To Do List. Now submit your changes and edit the default group again.
