[Mailman-Users] Mass Subscriptions and setting passwords?

[rubish-heap at rogers.com]

I've been trying to setup a password minimized list in version 2.0.13 as per the instructions in FAQ 3.11, "How do I create a newsletter/announcement/one-way list?".  Unfortunately, the FAQ doesn't seem to work (at least for 2.0.13) in that messages sent to <yourlist>-leave at dom.ain (properly modified for my list and domain) do not create a confirmation message for unsubscribing.

To get around this, I've been attempting to create a list that uses a fixed password for everyone.  When that is the case I can simply send a message with the password included in the body of the message ("unsubscribe wino at beer.com md2020").  

So the real question that I want to mass subscribe my current users without sending out confirmation letters and setting their passwords.  Anyone know how or if I can do this?
