I will be doing 2 corrective sheets for the IE6 and IE7. Outside of that the browser must pass Acid 2. That's 99.9% of the browsers out there. Firefox 2 is the most common browser that doesn't fall into this group.

Browsers that don't support CSS properly need to die. If computing in general progressed with the same attitude that web sites have regarding old browsers we'd be seeing new software shackled to the capabilities of 486 computers running Windows 3.1 -- or worse Commodore 64's and Apple II's. There comes a time to die.

vBulletin's current default set supports browsers as old as Netscape 4 and IE 4. To be honest, that's a ridiculous amount of backward compatibility equivalent to a video game desinger making sure his newest game can run on a Playstation 1.
