I don't understand the problem. If you want your mail from this list to have a subject that looks like: [LSTOWN-L] Subject-Tag all you have to do is send mail to [log in to unmask] or to [log in to unmask] (depending on which one you're subscribed on) with the command: SET LSTOWN-L SUBJ The list does not need anything special done to it. Subject-tag= is only if you need to use a tag different than the list name. And no one is forcing anyone to use the subject-headers. Anyone who wants it can SET it, and those who don't, don't have to.It's all up to each subscriber's individual preferences -- what's worth discussing? Puzzled, Francoise
