Dear NARCCAP "Extremists":

	Thanks to all of you who have replied to my earlier emails.  I've been on
foreign travel and trying to get ready for the fall semester, so I've been
quiet.  However, I appreciate all the replies, and I'll try to move
forward from there, working with the NCAR folks to post appropriate
further information.
