I'll offer 3 comments (but I think no surprises) ... You haven't told us what they were screaming, nor we know how the Yahoo Group or LISTSERV list was setup, nor do we know how you prepared them for the change, except to say a change was coming. It's hard to comment w/o something more concrete. Except in very special, brief circumstances, I've always had a policy that discussing the list or problems one has with the list is off-topic and not welcome on-the-list! Whenever there is something new, people get frustrated, and with some, the frustration turns to anger beyond reason. Some people skip right past frustration and express their anger immediately (Case in point: the idiot on TV with Mike Meyers from LA this past weekend). I had one list where I setup another list for discussion of the first. It was used for a couple of years (until the membership matured). Yahoo Groups offers a beautiful interface, albeit with advertisements. LISTSERV offers a very good interface with tremendous capability and flexibility, but not quite as slick when used for the first time. Also, a list owner has more freedom to tailor the LISTSERV interface to the audience. Hope this helps! cheers, wayne C.
