[nabs-l] Thunderbird question

[Beth Taurasi]

Hi, all.
I have a Thunderbird question.  How do you guys use Thunderbird's 
Address book to send to multiple email addresses?  I'd be doing this 
before the mental health and other disabilities listserv comes up on the 
NFB, but I'd like to control, for now, how many people get said emails 
from me.  I'm kind of new to Thunderbird, so help me out here.
