Interestingly enough, the sample HTML pages for MLM don't work. I've gotten an older version to work on a different server. I can create new lists (with admin login). I can add users (with admin login). When I load the original HTML from the web server so I can use the web interface like normal users would, they don't work. In fact, the two pages that are supposed to show all my lists (using subscribe_auto_multiple and subscribe_auto_single) don't return a list of mailing lists like your website does. I only get a "-1" checkbox or "-1" in a pull down list. But on the server, in the lists directory, I see all three of the lists with the appropriate file names and four extensions (.in, .lock, .out and .txt). All of those files have 777 permissions, so it should work.
