simple form within server form in asp.net?
<p>I have a strange situation...(strange for beginners like me not for experts:)</p>

<p>In my pages from my web site I have:</p>

<pre><code>&lt;form runat="server"&gt;
  &lt;!--some user controls--&gt;
  &lt;form action="http://gramma.us1.list-manage.com/subscribe/post?u=64d2cf63fb98f334f406892db&amp;amp;id=f3181fb3be" method="post"&gt;
  &lt;!-- rest of newsletter code --&gt;
  &lt;/form&gt;
   &lt;!--other user controls--&gt;
&lt;/form&gt;
</code></pre>

<p>As you see, that nested form is from some generated code from mail chimp newsletter subscribing html code.</p>

<p>Of course, this does not work. (the page is successfully rendered but the form posting does not work)</p>

<p>The question is:</p>

<ul>
<li>which is the work-around to make this nested form to work? I cannot use multiple <code>runat="server"</code> forms in my page to separate the main form from the nested one...</li>
</ul>

<p><strong>UPDATE</strong>:</p>

<p>The entire code from mail chimp...</p>
