[Mailman-Users] Possible to allow web-unsubscribe without a password?

[Kip DeGraaf]

My boss wants to have a list, but wants it absolutely easy to unsubscribe
from and wants me to have a link at the bottom of every message that will go
to a page for unsubscribing.

But he doesn't like the password requirement and he doesn't care that it
prevents people from unsubscribing others.  He wants people who want out to
be able to do it as quickly and as painlessly as possible.

Is there a way to configure Mailman to allow this?
