Unfortunately I can't seem to "Check out the blank repository" as per the instructions here:
http://wordpress.org/extend/plugins/about/svn/#task-1
This is the error:
Checkout from http://plugins.svn.wordpress.org/mailman-widget, revision HEAD, Fully recursive, Externals included
URL 'http://plugins.svn.wordpress.org/mailman-widget' doesn't exist
So, unfortunately, this plugin will remains unreleased until this is resolved.
