+<p>
+There are two mailing lists for the Golden Cheetah project:
+
+<p><a href="http://groups.google.com/group/golden-cheetah-users">Golden
+Cheetah Users</a> is a list for submitting bug reports, feature requests, and
+constructive criticism.  It's a good place to search if you have a question
+that someone might have already answered.  It's also where we discuss new
+features, plans, etc.  On busy days there may be as many as 20 emails sent to
+Golden Cheetah Users.
+
+<p><a href="http://groups.google.com/group/golden-cheetah-announce">Golden
+Cheetah Announce</a> is a lower volume, moderated list where we post
+announcements of new releases, important bug fixes, etc.  If you don't want to
+get a lot of email, but you do want to know when we put out a new release,
+this is the list for you.  It receives one or two emails per month.
