[Mailman-Users] User Management

[Douglas D. J. de Macedo]

Hi people,

I would like to know more about user management on Mailman system.

My problem is that I have more than 50 lists and every time time that one of
the users go out of the company I have to go one per one list removing this
user. And the other way, when a new person get a job here I have to sign
their email list per list ..

So there are some tool to help me?

Thanks in advance.

Doug
