[Mailman-Users] Subscribing to Mailman

[Blackbird]

hello.  I need some help.

Is there a way to subscribe to a mailman list without having to go to the
users' page and filling up the subscription online form?

I used to use majordomo and interested parties can subscribe via email.  I
even put a form on a web site where one can fill in their email address, and
a script just sends that email address to the mailing list.  Would Mailman
have a similar feature?

Thanks.
