[Mailman-Users] Mailman forms

[PeteBell]

Is there a way to find out what forms have are available for Mailman 
cgi scripts?

I have successfully incorporated the "subscribe" mail form into my 
website, but would like to be able to use a form to UNsubscribe 
(currently, you have to go to the options page and enter your password, 
but it is possible to unsubscribe by email with password authentication 
in the one email, so how can I have this in the form of a form!?

I'd also like to do the same with "delivery off/on" and other features. 
  Is it "FormMail" Mailman uses? Or cgiMail? or what?

Cheers
