The download pages for Fedora Server 21 Beta (https://fedoraproject.org/en/get-prerelease#server) and Fedora Workstation 21 Beta (https://fedoraproject.org/en/get-prerelease#workstation) direct support questions to the mailing lists server@lists.fedoraproject.org and desktop@lists.fedoraproject.org respectively.  Yet there is no response to e-mails directed to these lists.  An examination of the archives of these list indicates perhaps a different level of discussion.  Please advise.
