Newsletter subscribe

I am attempting to have the newsletter subscribe on signup.php. It is showing in the code but it is not showing on the site. Could someone please tell me how to have the newsletter option available on signup.php form?

On signup.html

{if $newsletter_threads > 0}
<tr>
<th>#_TPL_SIGNUP_NEWSLETTERS_SUBSCRIBE#<br />
<div class="small">#_TPL_SIGNUP_NEWSLETTERS_SUBSCRIBE_1#</div>
</th>
<td><input type="checkbox" name="to_subscribe" value="1"
{if $smarty.request.to_subscribe}checked="checked"{/if} />
</td>
</tr>
{/if}

Remove the if statements and I suggest changing the
{if $smarty.request.to_subscribe}checked="checked"{/if} />
to checked="checked" />

Thank you!
