Hi,

I don't find any place to raise an issue so I'm raising it here, please let me know if there is a better place.

During the last contest, I used the light version of Codeforces (m1.codeforces.com) and apparently while submitting the problem D (div 2), it submitted it twice and I got a 50 pts penalty.

Thanks
