Dashboard system messages are a way for you to communicate with your site users. Typically, welcome messages, links to user guides or brand guidelines, quick instructions about how to perform an action within the site, admin contact information and more are featured in system messages.
System messages display in the System Message zone on the Dashboard. Users can rearrange the zone's location on their Dashboard by dragging and dropping it within the column.
More than one system message can be displayed, but users will only see the message(s) enabled for their role.
