I maintain the Advanced User module and just haven't had time to look at the issues. My time has been totally used by real life work and family life recently and I do not foresee that changing in the near future. It the meantime there are some annoying issues that users are seeing and I haven't had time to research them. Please contact me via the http://drupal.org/user/86710/contact web form if you are interested in helping. -- Earnie
