This is generally not necessary and my be undesirable for several reasons. If you make a change to the Default-Options= settings and want them to apply to all subscribers, you can simply send the command: QUIET SET listname desired_options FOR *@* For example, in the case under discussion that would be QUIET SET listname NOPOST FOR *@* You generally want to use the 'QUIET' modifier so LISTSERV does not send out a notification to all list members. It not only saves wear and tear on the server it also saves the List Owner from having to respond to a dozen or so 'What the heck?' kind of queries.
