Ok, we will think about it. My first comment is: As long as these system notifications to the end-user are still diffcult to understand and may get lost, it is safer to have somebody get a copy. See for instance this bug
https://openacs.org/bugtracker/openacs/bug?bug%5fnumber=1768 regarding ext auth awareness of a similar message.
In the medium future, a distinction is desirable between routine user adminstration, and (potentially dangerous) system / security admistration. See also
