The other brings the user to a separate page, but returns the user to their original page upon login.</li>\n <li>Customize the registration form with two e-mail fields to ensure accuracy.</li>\n <li>Optionally redirect the user to a specific page when using the 'Immediate login' feature.</li>\n <li>Optionally redirect the user to a specific page upon validation of their e-mail address.</li>\n <li>Optionally display a user message indicating a successful login.</li>\n <li>Optionally combine both the login and registration form on one page.</li>\n <li>Optionally display an 'Request new password' link on the user login form.</li>\n <li>Optionally have unvalidated users purged from the system at a pre-defined interval (please read the CAVEATS section of INSTALL.txt for important information on configuring this feature!).</li>\n </ol>\n These features may be turned on or off in the Login Toboggan <a href=\"!url\">settings</a>.</p>\n <p>Because this module completely reorients the Drupal login process you will probably want to edit the welcome e-mail on the <a href=\"!user_settings\">user settings</a> page.
