[Mailman-Users] Getting all names and addresses from a list

[Jean Stora]

Hello,

I use mailman 2.1.9 cp2.

Hypothetical data:
site: www.mysite.com
List name: news

I am using the web interface only to modify the list, that means I am not at the server.
I need to export the entire list of names and email addresses.
I have had a hard time but finally got this imput to give me the email addresses:
http://mail.mysite.com/mailman/roster/news_mysite.com

I have 2 problems:

1- I am able to only get a partial list because somehow it's hiding some private members.
2- I need the names as well.

Can you help solving the problem....

I need the entire list to display including names and email addresses.

I had a look at the archives and info like: 
To export the list of users subscribed to the list:
 ~mailman/bin/get_members <listname> 

But I can't figure out how to use that command... do I insert it in my url request in the browser?

Help....

Thanks

Jean
