Unsubscribing/managing subscription for a LSST mailing list hosted by SLAC

I want to unsubscribe from a LSST mailing list hosted by SLAC. I end up on this page:

http://srs.slac.stanford.edu/GroupManager/exp/LSST-DESC/protected/mailLists.jsp?getlist=LSST-DESC-CLUSTERS

Takes me to:

SLAC Central Authentication Service (CAS)

This does not have a password reminder option.

Hi Richard, you should be getting an email from Charlotte at SLAC, who manages the LSST-DESC stuff, to help you out.
