Details
The advanced user module allows the filtering of users based on the user.module fields and optionally the profile.module fields. The fields available for filtering can be configured using the module settings. Eg. Site admin may search through 1000s of users to display all users who have not accessed their account.
Once the group of users with selected common denominators are filtered, the module can be used to perform functions that email, block, unblock, add or remove roles, or delete. Another nice feature is the ability to notify administrators or other roles, by email, of user account creation or profile changes.
I am looking for a co-maintainer of this module. Please let me know of you interest using the contact form.
NOTE: Version 6.x-3.x or 7.x-3.x is the release to use. The Drupal 6.x-2.x-dev release is no longer being updated.
advuser-6.x-3.x
Pay close attention
I have begun the modifications for feature enhancements. The module directory and file structure is being changed. If you upgrade to this version of the module you will need to completely remove the previous version of the module (cd sites/all/modules && rm -rf advuser) before installing this version.
advuser-7.x-3.x
The -dev version is functional
I have converted the Advanced User to Drupal 7 using the 3.x series. You should be able to use this module in your Drupal 7 environments. I will be creating a release candidate by June 30th, 2012 or before.
