I changed the design of the site slightly because I noticed it was getting a bit chunky in the graphics dept., so I slimmed it down a bit.
There's a nifty little CSS rule called -moz-border-radius that I'm using in this current design. If you are using Firefox to view this site you will see nice roundy borders, like this:
Notice the rounded corners on the white boxes.
If you are using Internet Exploder Explorer, you will see regular squared corners like this:
Either way, the site is still plenty readable in IE 7 or Firefox 2.
