This year at the IOI (International Olympiad in Informatics), there will be an Internet Contest.
It's exactly the same as the real contest, and [s]at the same hours[/s], only you can't get a medal.

I will be on site, so you know you want to participate online, just so you can see how badly I can kick your ass. :)

Edit: Oops. Not same hours. Internet contestants get 24 hours. (Official competitors get 5.)

Are you going to the real one again?

Yes :) It's next week.

You should tell the US guys to invite me, I wouldn't help much, but then we could stop cybering and do the real thing!
