If you don't have a black background at your homesite, you probably see that your background image or color ends a bit above the bottom margin of the page and there's a black space where it says "Copyright 2002...." Here's a way to get rid of it:

For background colors:

<style type="text/css">
.community { background-color: #yourcolorhere; }
div { background-color: transparent; }
</style>

For background images:

<style type="text/css">
.community { background-image: url("yourimage.gif"); }
div { background-color: transparent; }
</style>

This works in IE 6 and NS 7. I hope it helps.
