    We have absolutely no problem with Iranian committee helping us to hold the competition together. In fact, if you check the mathematics competition jury, you will see that the problems are prepared by an Iranian olympiad coach Morteza. We sent an invite to all IOI participant countries to participate and let us know if they have any feedback/suggestions.

I'd like to participate, but unfortunately the connection to the site does not support HTTPS encryption, so personal data put there could be seen by our ISP or crackers. I'd be very happy if you or another person fixes that.

Thanks for reading.

    No worries about security. Just use the password that you don't use anywhere.

Should probably mention its been extended to 120 hours. I nearly commented here about one of the problems before seeing there was 40 hours remaining on the ranking page.
