Subject: Are you getting more mails than you'd like?
             -- 
You could have the digests instead of individual e-mails.  The way to 
do that is to simply join with a blank mail:
Ferret-Health-list-subscribe@yahoogroups.com  (You can skip this part 
if already a member.)
and afterward select digest by sending a second blank mail to:
Ferret-Health-list-digest@yahoogroups.com .
This is in  the joining materials but sometimes gets overlooked or 
lost in the ether, so here's a reminder.
