Can I suggest that voting/rating would be part of a bit of an overhaul of saberfont.com...
Basically, to allow people to vote, you'd want them to have registered, to stop people spamming/abusing the vote system. In a perfect world you'd want to have some way to check they'd bought the font too, but that's even more complex. Anyway, if you're registering users, it would be an ideal time to fix the whole download cart mess. Currently when you buy a font, you download it then and there, or you've lost it. Purchases should be tracked and tied to your account, so you can re-download in the future should you lose them for whatever reason. Which then ties back into the earlier part about tracking votes etc.
I know this answer is way out of the scope of what you asked, but theres that old saying about if you're going to do a job, do it right...
I know its all a work in progress and I think everyone appreciates the work that has been put into it, just my 2c...
