Process HTML form on aspx page

 Hey everyone. My problem is I need to make an html form that can pass data to an asp.net page. That asp.net page then takes the information sent from the form and adds it to a database. This is what I have so far.
 
   <form action="~\OptIn.aspx" method="post">
                ...blah
              ...blah
               <input type="Text" name="Email" size="65" style="font-size: 11px; font-family: Verdana"></td>

               <input type="submit" name="submit" value="OK" />  </td>
           &nb ...
