Yes, well, if you find yourself cross-posting things over an extended period of time, as opposed to an occasional discussion on a particular topic, there is clearly something wrong. Since your topic is relevant to multiple lists it is likely that many people will be subscribed to more than one of these lists and they probably aren't looking forward to multiple copies of a discussion over an extended period of time. So the best thing to do is select a list to hold that discussion and invite people who are interested to join it. Eric
