I took the output from that and fed it into Email Extractor which gave me the results of each of my lists in a text file, which is what I was trying to get -- so I'm happy that I've at least done what I wanted to do.
Still, if there's a way to just click a button from within MBM or the web interface of MLM that would definitely be easier and more desirable for me.
Yes, from inside MaxBulk Mailer, go to the 'Recipients' panel, click on the 'List' pull-down menu, select 'Remote Lists', click the list you want to export and finally click on the 'Export' button.
