mystery code

[forte]

Hey errbody, I've been working on a project and I was going through my headers when I spotted these codes:
<script type="text/javascript">
<!--
document.getElementsByTagName('table')[0].cellSpacing = 0;
//-->
</script>
<script type="text/javascript">
<!--
document.getElementsByTagName('td').item(2).style.display="none";
//-->
</script>

They didn't change anything that I could see on my test board, and I don't remember adding them or where I found them. If anyone recognizes them could you please tell me what they're for?

The first one is used to remove the border from the welcome table and the second one hides the "Hey x, you have x messages..." cell.
