title: Multiple forms in an HTML page posting to itself
body: <p>I need to have multiple forms in the same webpage, all of them POSTing to itself and then performing different actions depending on the type of form.</p>
  
  <p>What's the best way to achieve this?</p>
  
  <p>To be more specific, the page shows the details of an event, with a form to subscribe (a drop-down box) and another form for each of the subscribed persons that allows them to unsubscribe (it's just a button).</p>
