I rember that my problem was already discussed some time ago, but I can't remember the result/solution: For a couple of Lists I run, List members should not be able to UNSUBSCRIBE themselfes. They have to join some Lists. How can I achieve this? best regards Hermann Schneider ____/ ____/ __ / ____/ CS Computer Networks coordinator / / / / / Robert Bosch Strasse 5 /___/ ___ / / / / D 64276 Darmstadt / / / / / ____/ ____/ _____/ ____/ Phone: (49) 6151.90.2464 European Space Operations Centre Fax: .3061
