 154      <h3>What does this do?</h3>
 155      <p>Display's a contact form. This can be used to allow others to send an email message to the address specified.</p>
 156      <h3>How do I use it?</h3>
 157      <p>Just insert the tag into your template/page like: <code>{contact_form email="yourname@yourdomain.com"}</code><br>
 158      <br>
 159      If you would like to send an email to multiple adresses, seperate each address with a comma.</p>
 160      <h3>What parameters does it take?</h3>
 161      <ul>
 162          <li>email - The email address that the message will be sent to.</li>
 163          <li><em>(optional)</em>style - true/false, use the predefined styles. Default is true.</li>
 164          <li><em>(optional)</em>subject_get_var - string, allows you to specify which _GET var to use as the default value for subject.
 165                 <p>Example:</p>
 166                 <pre>{contact_form email="yourname@yourdomain.com" subject_get_var="subject"}</pre>
 167               <p>Then call the page with the form on it like this: /index.php?page=contact&subject=test+subject</p>
 168               <p>And the following will appear in the "Subject" box: "test subject"
 169             </li>
 170          <li><em>(optional)</em>captcha - true/false, use Captcha response test (Captcha module must be installed). Default is false.</li>
 171      </ul>
 172      </p>
