> the wider problem case is how non-subscribers are given two-way access to the list that exposes so much subscriber info (name, professional affiliation, email addr, ...) to whomever. i cannot fathom why the list does not make use of aliases so that each subscriber can control what they want to make public via their alias profile. List membership is not public . Only members can post to the list. Not sure what else you think we are doing wrong.
