I mean that on the web page where one signs up for the datatracker, or registers for a meeting, there should be a *pre-ticked* box for "Join the XXX@xxxxxxxx mailing list". In fact, a list would be even better; thinking out loud: [/] important@xxxxxxxx -- important IETF announcements [/] ietf-announce@xxxxxxxx -- general IETF announcements [/] ietf@xxxxxxxx -- general discussion list [/] agenda-announce -- meeting announcements of all kinds [/] last-call -- IETF-wide document last calls [/] I-D-annnounce -- Internet Draft announcements [/] rfc-announce -- RFC announcements [/] datatracker -- general data tracker announcements and maybe one or two more. And set "no duplicates" in mailman for all announcement lists. Brian
