[thelist] Submitting contents of form only once

The easiest way (and maybe only way) would be to make changes such as the

<script lang...>
  var submitted = false;
  function check_submit()
     if (submitted) return false;
     return (submitted = true);
     // only one equal sign because it's being set too

<form method="..." action="..." onsubmit="return check_submit();">
  <input type="submit">

To protect yourself on the server side you might think about including a uid
in a hidden form field that gets recorded somewhere (session variable and/or
with the record) and then you can do a quick check to make sure the request
not already been processed before continuing.

Hopefully that helps.
