Topics like How to hide staff alerts at the top of page? come up on a somewhat regular basis here on Meta. Most of the time users were concerned that the alerts would be visible to their community members, and after explaining that the alerts are only visible to admins they no longer viewed the alerts as an issue.
Long time Discourse admins know that the alerts are admin only, but how is a new Discourse admin supposed to know that. There’s no visual indication for the user to know any different. I’d like to propose something similar to what Slack does and add some text explaining the alert’s visibility.
