In reply to David.

The word "admin" (for notices) could be interpreted in two ways -- either they're admin / back-end notices, or they're administrator notices. I've always understood that they are the former (notices displayed on the admin back-end), and can be seen by any / all back-end users, so I use "current_user_can()" in my own code to display different kinds of messages. Maybe this is more of a developer awareness issue than a core WP issue. ;-)
