I have an owner who needs to send duplicate messages and has asked for
their list to be configured to accomodate this.

How dangerous is this?  It isn't a public list (it is a student list for
a course taught here at U of G).  Ideally, I'd like this one user, the
owner, to be allowed to send duplicate messages to this list and no one
else.  Is this level of granularity available, or does this setting just
work at the list level?

Thank you very much for your assistance.

Cheers
Sean
