The demo site is back up again at https://demo.horde.org/stable/horde/ It currently has demos of IMP-3.0-stable and Chora-1.0-stable. Other applications will be forthcoming as the machine is more fully installed. The SSL certificate is self-signed. If anyone can purchase a certificate for demo.horde.org from a proper CA and donate it to us, that would be appreciated. Anil
