Actually, yes. Vote 1 and 2 are once a day, and vote 3 is every 12 hours. Also, what is so scary about having an every 24 hours site...?
They reset at a certain time, not after a certain time. PMC for example was to strict. Living in England (GMT timezone), gives me a very flexible time schedule on vote 1 and 2. Vote 3 is a different story.
And that's correct... but what's wrong with a vote site resetting after 24 hours? That would almost encourage further competition for the vote medal... plus, PMC brought in a huge amount of new players back in the day.
I think it would be ok, personally. It's been practically the same people winning the medal over and over every month...
