How to unsubscribe?
To unsubscribe from a list, send an email to
listar@linuxfromscratch.org and write unsubscribe
listname in the subject line of the message.
You can, if you want, unsubscribe from multiple lists at the same time
using one email. If you want to do so, write some junk in the
subject line, something that isn't a valid command like "hello". Then 
write the unsubscribe commands in the body of the message. The email 
will look like: 
To: listar@linuxfromscratch.org
Subject: hello 
unsubscribe lfs-discuss
unsubscribe lfs-apps
unsubscribe alfs-discuss 
After you have sent the email, the Listar program will send you an 
email back requesting a confirmation of your unsubscription
request. After you have sent back this confirmation email, Listar will 
send you an email again with the message that you have been unsubscribed 
from the list(s).
