You should be able to do everything you need with the site password --
it's a master password that gives administrative access to 
everything.  

If you don't know the site password, you can set a new one by
running

   $prefix/bin/mmsitepass

Replace $prefix with the directory that Mailman is installed in.
You'll need to be root or the user that mailman runs under when you
do this.  

Now you can use your new password to access any list.
