If you have ever wanted to be notified of something in RT, and share it with others—to followup on a set of tickets monthly, for instance, track the status of a queue, or group a set of different saved searches all related to the same project—you can set up notifications with dashboards: named, shared collections of saved searches.
"Dashboard Notifications - a Quick Introduction," a PDF tutorial by our own Ruslan, shows you how to use this new feature in RT 3.8.
