One must know who we are dealing with. A bot perhaps?<form method="POST" id="su">
    Create Name/Username: <br> <input type="text" name="name" />
    <br>
    Create Password: <br> <input type="password" name="pass"/>
    <br>
    Already one of us? Click <a href="login.php">here</a> to login.
    <br>
    <br>
    <input type="submit" />
</form>
