May I should have clarified: This is an announce-only list where we are
sending out monthly newsletters to our customers. Therefore, they have no
idea that there is a "webpage" that allows them to setup their account or to
modify their subscription settings. Basically, they have no idea that it is
mailman that they are using.
I just setup an html form that automatically sends an e-mail to the
list-subscribe at domain.com e-mail address to subscribe and sends an e-mail to
list-leave at domain.com e-mail address to unsubscribe users.
They have no interaction with the default mailman web interface.

Since I do not want the e-mail list to be viewable by potential spam
harvesters, or even  the other subscribers, for that matter, I do not want
the list roster to be viewable by anyone other than myself.
