I REALLY need and easy way to grab the entire subscriber list. I am admin of this list and currently only use the web interface.
FAQ at list.org:
3.4. How do I move a list to a different server/Mailman installation. Robin Rowe's quick tip: There's already a mass subscribe feature in the interface. All one needs is the member list from the old list. To get that, send a blank email to yourlistname-request@yourlistserver.com with a subject of 'who yourpassword'. The list admin password is only necessary if you have the members list locked to admin access only. Otherwise, you could just use 'who'. The automated email response will contain the list of names from the list. You can cut-n-paste that text into the {Membership Management}{Mass Subscription} field in the interface of the new list.
