[Mailman-Users] mass subscription

[Rob Eckerson]

I want to mass subscribe people that I have on another list. I want to just send them an email with a link to subscribe( cutting out the confirmation email). These people have already opted in to receive email from me. 
Also, I noticed that when you mass subscribe a password is assigned. Can I make a static password, rather than having to run the change password script.
Any help would be appreciated.
