I hate Internet Explorer. If you happen to be unfortunate enough to be using it, please, consider either upgrading to Firefox or convincing the people in charge over in IT to give it a shot. Firefox actually supports web standards - those neat things that make it possible for people to write all sorts of really neat web pages, without having to resort to evil nasty hacks.
I have no idea what this page looks like under IE5. My closest guess would be that it looks like a plate full of ass, and if it does, then too bad. There are at least a half dozen other web browsers you can use that will render this site properly, and if all else fails you could always upgrade to IE6 since that works for now.
In the future, my "compatibility" with IE is going to consist of hiding things that the browser doesn't understand, instead of trying to get it to work.
