As it seems, Opera renders it mostly correctly (significantly better than FireFox), and their reps say they're working on passing it completely.
Safari passes it now, but the version that does isn't available yet. The same goes for Konqueror (I think).
They don't really say how they calculate the score, do they? "Your score is relative to other AIM users?" What the hell does that mean? Why isn't it just the number of third-degree connections, what's wrong with using that number?
They do say how they calculate the score, and it does use the number of third-degree connections.
Right on aimfight.com, if you click "What is AIMFight?", the second FAQ answer is:

Why can't there be some Firefox extension that puts a button somewhere so that if a web site seems to be fucked up, clicking the button sends an email to webmaster@siteyouarelookingat.com complaining about their lack of compliance to standard?
FireFox 1.1 (Well, at least Deer Park Alpha 1) currently does something similar to this.
<? if (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== false && strpos($_SERVER['HTTP_USER_AGENT'], 'Opera') === false) { ?> <b>Warning:</b> You are using the Microsoft Internet Explorer browser. This browser is notorious for its inability to comply with W3C standards. In other words, IE sucks.<br/><br/> So what should you do? We reccomend you install <a href="http://www.getfirefox.com/" target="_blank" >Mozilla FireFox</a> instead. <? } ?>
Replace the stuff between '{ ?>' and '<? }' with whatever you like.

It actually stands for Windows Future Storage, not Windows File System, and is not a filesystem, but instead a 'plugin', of sorts, to NTFS.
I think browsers use a different string (HTTP-Accept) to say what they support. User-Agent is just to say which browser it is.
