The Broadcast Widget allows the system administrator to see which users are logged into Workgroups and also compose messages that can be sent to specific users. Access to the widget is based on permissions, but it is highly recommended that only system administrators are granted this access.
To access the widget, click Configuration > Configuration Dashboard
Once the dashboard loads, you'll add the 'Broadcast' widget
The widget will be added to the bottom of the dashboard and you'll be able to see which users are logged in
In the upper right corner of the widget there is a 'Compose Mail' button that allows you to send a message to specific users of the system that you select in the popup
The message will be sent to the email associated with their account
Once you've composed the message, simply click 'Send'
