any chance on IE 8 becoming more StartCOM website friendly? I know there are some issues with sections of your site using IE 8...

Which ones?

I tried to register a S/MIME cert in IE 8 and it failed miserably.

On windows 7 it bailed when creating the cert and on XP it seem to create the cert, but i don't seem to be able to use it in mumble (maybe this is because the IE8 certificate format differs from .pk12 that firefox generates?). On XP there were ton of missing images and the fonts looked kind of funky.

Are these issues still going on? I remember there were issues with IE 7 too...ah yes, here:

Do yourself a favor ya'll and switch to Firefox or Chrome.
