    <h3>What does this do?</h3>
    <p>This tag renders a small "Tell a Friend" form, which automatically includes the URL of the page the form is on. The user fills in their name and email address, the recipients email address, and optionally a message. Pressing submit sends an email to the recipient.</p>
    <p>This tag is a mashup of the contact_form tag and some code <a href="http://forum.cmsmadesimple.org/index.php/topic,8827.0.html" target="_blank">posted in the forums</a> by <b>samalah</b>. This tag was created to offer something more formal than a mailto link, and something more spam-resistant than a plain form (through Captcha support).</p>
    <h3>How do I use it?</h3>
    <p>Just insert the tag into your template/page like: <code>{tellafriend_form emailsubject="Check out this page at foo.com!"}</code><br>
    <br>
    </p>
    <h3>What parameters does it take?</h3>
    <ul>
    <li>emailsubject - The subject of the email that will be sent.</li>
    <li><em>(optional)</em>style - true/false, use the predefined styles. Default is true.</li>
    <li><em>(optional)</em>cannedtext - Used to include some default text in the message field. If you omit this, the message field will just contain the page URL.</li>
    <li><em>(optional)</em>captcha - true/false, use Captcha response test (Captcha module must be installed). Default is false.</li>
    </ul>
    </p>
