Hello guy... I also had to use this editor... To retrieve its content you have to add this code:

<form action="#" method="get">
<script src="editor/js/richtext.js" type="text/javascript" language="javascript"></script>
<script src="editor/js/config.js" type="text/javascript" language="javascript"></script>
<script type="text/javascript">
initRTE('', 'editor/examples/example.css');
</script>
<input type="submit" onClick="javascript:takeContent();" value="Submit Form">
</form>

<script type="text/javascript">
function takeContent() {
alert(getXHTML(trim(document.getElementById(rteFor mName).value)));
}
</script>

But it's impossible to take the value of the content if you don't put in the Code Mode first.
