/blog/feed is not found after this module is installed.

I added the following at the top of function _mass_url_user_page() , right after the $url_username assignment.


  if (($page_type == 'blog') && ($url_username == 'feed'))
        {
        blog_feed_last();
        return;
        }

This fixed the problem but may not be the way you want to do it.
