Custom Registration Template/Page

Here is a function I’ve Used Before:

function registration_form_wpa95139(){
    if (is_user_logged_in()) return;
    ?>
    <div class="Registration">
        <div id="register-form">
            <div class="title">
                <h1><?php _e('Register your Account'); ?></h1>
                <span><?php _e('Sign Up with us and Enjoy!'); ?></span>
            </div>
            <form action="<?php echo site_url('wp-login.php?action=register', 'login_post') ?>" method="post">
                <input type="text" name="user_login" value="Username" id="user_login" class="input" placeholder="Username" />
                <input type="text" name="user_email" value="E-Mail" id="user_email" class="input"  placeholder="E-Mail" />
                    <?php do_action('register_form'); ?>
                    <input type="submit" value="<?php _e('Register'); ?>" id="register" />
                <hr />
                <p class="statement"><?php _e('A password will be e-mailed to you.'); ?></p>
            </form>
        </div>
    </div><!-- /Registration -->
    ?>
}

and you can call it like this:

<?php registration_form_wpa95139() ;?>
