Adding users

["Mike Horton" <support @ klings . com>]

I have Majordomo set up and working just fine. What I need to know though,
is if anyone knows of an easy way to get about 150 linux users all
subscribed to the list without entering them all by hand. Is there some
way to get Majordomo to look at my password file and add all the users
automatically.
Thank you
