You may need to know about EZBoard to help me out.

I have a board @ www.ezboard.com. Inside my control panel there is a "Custom HTML" section. In this section I am trying to add:

<html>
<body>

<script type="text/javascript">
alert("My Message Here")
</script>

</body>
</html>

====
I am trying to make it so that when someone comes to my board it will pop-up a little message window. Everytime I type in the script and save it it automaticly changes every "script" to "******" Of course this screws up the script and it displays crappy looking code on the page. (

Any help would be greatly appreciated!

Thanks in advance.
