Majordomo management

Hi all;

I've got my new PostgreSQL Users Group up and running including my new
mailing list (diapug(at)postgresql(dot)org) -- Thanks to Selena and Marc !

However I'm completely new to Majordomo.
Can anyone point me to some good docs as in say a quick start guide ?

Also I'd like to have a page similar to the PostgreSQL lists signup page
(http://www.postgresql.org/community/lists/)
Can I get our User Group added here? or Is this page part of a web based
Majordomo mgt tool I can download and host myself somewhere?

Thanks in advance...
