How are they doing this--by having each student sign himself up?  This
must be a royal pain in the butt for the instructors.
You could probably make their lives much easier by offering a "bulk
signup service" where a professor can sign up his whole class just by
sending you a list of all his students' e-mail addresses (which he
probably has online anyway).  Then send that file to listserv as a
bunch of adds at the start of the semester and a bunch of dels at
the end, which should take you maybe ten minutes total.
 
Of course, you would never do something like this simply to make
your own life easier, only as a service to your users ;-).

Well, when I do a "query centam-l for *@*" it sure looks to me like I'm
getting the concealed users.  Or is your difficulty in something other
than learning the addresses?
