WordPress MU

I've learned that WordPress comes bundled with TinyMCE by default.

I visited the TinyMCE homepage and copied the simple example source code:

<script type="text/javascript" src="<your installation path>/tiny_mce/tiny_mce.js"></script>
<script type="text/javascript">
tinyMCE.init({
	mode : "textareas",
	theme : "simple"
});
</script>

<form method="post" action="somepage">
	<textarea name="content" style="width:100%">
	</textarea>
</form>

I remove the following:

<script type="text/javascript" src="<your installation path>/tiny_mce/tiny_mce.js"></script>

I added the following:

add_action('admin_head','my_tiny_mce');
function my_tiny_mce() {
    wp_enqueue_script('tiny_mce');
}

However the result is just an empty textarea.

I've tried using the code in this similar post but didn't have any success.

I also found this thread which uses the_editor(). I was able to get it working except for the ever so important visual/html view.

Can you please help me include a visual/html editor in my custom plug-in? Thanks!
