Several other modules exist for streamlining the account creation process. If you have a large number of users to manage, or if you are a system administrator at a school, you might want to look at these options:
Mass account creation and improved user management via the userplus module (http://drupal.org/project/userplus).
Import users from a csv file: (http://drupal.org/project/user_import).
Integrate with Lightweight Directory Access Protocol (LDAP) (http://drupal.org/project/ldap_integration). These modules include support for mapping LDAP groups to Drupal roles. See also http://drupal.org/project/ldap_provisioning.
To add terms and conditions, or an acceptable use policy, see the Legal module (http://drupal.org/project/legal).
