[Mailman-Users] Membership lists

I'm familiar with the "who <password>" facility to retrieve the membership listing, but is there a way I can receive this info with the individual settings for each subscriber? I'm particularly interested in members who have their mail delivery disabled, as I want to change them all to subscribe to the topic that I've set up specificially to be able to contact them all.

Is there a way to force everybody to subscribe to a topic when they first join the list, as this could save a lot of time in the future?
