The notes system allows for sending simple text messaging between OpsCenter users. If the recipient's status is "IN," the note will automatically pop up on the recipient's computer. If the recipient is not "IN," the note will be saved until they mark their status as "IN" or access the note from the My Messages window. Notes can be sent to a single user or a group of users. Old notes that have been archived can be accessed from the My Messages window. The notes system can be enabled and disabled by the administrator in the system controls.
