Messages and Requests Pane
The notifications area on the menu bar contains two buttons that point out to you the messages and requests you should take care of:
Clicking any of them opens this pane.
Messages
The pane displays the messages that have been output since your last login. The only exception are the administrator and security messages that have not yet been read.
The list is continuously updated and displays the messages in chronological order. Depending on the priority of the messages, the icon displayed next to Messages is gray (low), yellow (medium) or red (high).
Requests
Requests prompt you to take action on tasks. The number of active requests that are waiting for your response is displayed next to Requests.
