As we all know, the only browsers that display the BWC/BIS site correctly are IE and Opera. IE is bundled with your Mac, but Opera is either ad supported or fee-based software.
Opera is having a tenth anniversary party right now, and is giving away free registration codes while the party lasts:
http://my.opera.com/community/party/
It gives you a page of reg codes for Mac, Windows, Solaris, and various flavors of Linux.
Have fun!
