[Plugin: Theme My Login] Include nonce with logout?

What needs to be written in order to include a user’s nonce with the logout command?

I’m using the following for a loginout link, but when logging out, the user is directed to a WP failure screen. Here’s a screenshot: https://img.skitch.com/20101006-mggybsaa1xcs9tb3xi7g99rhi9.png

Heres the code I’m using for the loginout:

<div class="loginout">
   <h3>
      <a href="/login/?action=register">Register</a>
       &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;  ?????
       <?php
          if ( is_user_logged_in() ) {
             echo '<a href="/login/?action=logout" title="Log out">Log out</a>';
          } else {
             echo '<a href="/login/?action=login" title="Log in">Log in</a>';
          }
       ?>
       &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;              ?????
       <a style="color: darkOrange;" href="mailto:[email protected]">HELP</a>
    </h3>
</div>

If I can include the nonce with the logout command then the user will be successfully logged out with one click, correct?
