Mailman features are described here: http://www.list.org/features.html It is highly configurable and if it does not do something then I am sure it can be taught how to in 10 lines of Python, or less. I would not like to join a yahoo group, not because of the privacy issue, but because of the IP ownership issue. I do not post to the single yahoo list I am a member of if I can help it. Yahoo is owned indirectly by Microsoft and anything posted there becomes in part their property. They have perfectly good reasons for that. And I have mine for not posting there. If this list will move to Yahoo I will become a silent member, at most. Peter -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
