One of the non-Listserv managed lists I'm on has List-Archive and List-Unsubscribe headers such as these: List-Archive: http://www.imc.org/ietf-pkix/mail-archive/ List-Unsubscribe: mailto:[log in to unmask] These are helpful functions, but I don't believe they're available in Listserv as of the Unix 1.8d release. Are they available or planned for inclusion? Rich
