Here we go, the mod for the Preview button for the HTML, note variables like $username are not parsed in the preview.

Find:

PHP Code:

maketableheader("Preview of your TEXT email"); 


Above it add:

PHP Code:

    ?><tr class='firstalt' valign='top'>
        <td><p></p></td><td><p>
        <SCRIPT LANGUAGE="JavaScript">
        function displayHTML() {
        var inf = document.name.message.value;
        win = window.open(", ", 'popup', 'width=800,height=500,toolbar=no,status=yes,scrollbars=yes');
        win.document.write("" + inf + "");
        }
        </script>
        <input type='button' value='Preview' accesskey='p' onclick='javascript:displayHTML()'></p></td></tr>
    <?php

Thats it, you then get a preview button right under the HTML text area

Note: vB puts a space between java and script here: onclick='java script:displayHTML It should be javascript, one word
