I have posted some simmary information on the status of the TDWG Ontologies and Darwin Core on the VoMaG Group's Wiki at http://community.gbif.org/pg/pages/view/29079/a-review-of-the-tdwg-ontologie... There is a link to a discussion thread on the site. This is somewhat untested technology but Éamonn thinks the Group Discussion pages may be the most effective way to conduct discussions for the VoMaG group.
