User Management

This module is a little helper to maintain an administrator role which has all
available permissions. By default, Drupal only has one super user and this
module helps improve this drastically.

This module builds user profiles as content (aka nodes), which opens the opportunity to use all the powerful modules for content for user profiles too, e.g. the Content Construction Kit (CCK). It's intended to be simple and useful, but extensible by further modules.

Content profiles can be restricted to certain roles; the module also supports separate content profiles for different roles.

A CAPTCHA is a challenge-response test most often placed within web forms to determine whether the user is human. The purpose of CAPTCHA is to block form submissions by spambots, which are automated scripts that post spam content everywhere they can.
