Themed login makes it possible to change the look of default WordPress login system using 
templates located at your theme folder, not just CSS-level customizations:
<ul>
<li>Login – login.php</li>
<li>Lost password form – retrievepassword.php</li>
<li>Registration – register.php</li>
<li>Registration confirmation – registered.php</li>
</ul>
If your theme does not contain one of the files described above – that is not a big deal, 
WordPress’s defaults will be used. See usage examples in “examples” plugin directory.
