Due to a repeated pattern of commercial and political spamming on the cancer related mailing lists, we need to change something in the way new users subscribe. Specifically I would like to setup the lists to force every person issuing a SUB LISTXY to receive first a file containing the terms of service agreement. They would then have to respond with a prepared message: "yes I have read the terms and will abide by then". By answering this they will then be subscribed. Makes sense? How can it be done? * Gilles Frydman <==> [log in to unmask] * The Association of Cancer Online Resources * http://www.acor.org http://www.medinfo.org
