The Link checker module extracts links from your content when saved and periodically tries to detect broken hypertext links by checking the remote sites and evaluating the HTTP response codes. It shows all broken links in the reports/logs section and on the content edit page, if a link check has been failed. An author specific broken links report is also available in "My Account".

This module disables the "Username" field on user registration and user edit forms and generates a username automatically using a token or module provided pattern. The pattern could therefore be based on other profile fields (like first/last name), a regex version of their email address or a random string.
This module is complimented by logintobogan, which allows users to login with their email address (and therefore makes usernames redundant for the user, but of course still necessary for Drupal's backend - where auto_username fits in). The realname module also compliments this module, because it ensures any username displays are displayed as "Firstname Surname", which may be easier to read.
