Hah! A professor here recently made the mistake of mailing out his grade
sheet for a graduate course to his course's Listserv list. I was out of
town on vacation at the time. No one knew how to deal with the problem
and, of course, no one thought to consult L-Soft's documentation. Odds are
that by the time the unwanted posting was deleted, every student in that
course saw the full grade list.
