Last night I don’t want to sleep, so – I was working. I reread my old post "Contribution 2.0" (in Russian) and decided to implement some ideas. Taking into account the comments that everyone (no matter the color nor the position in the contribution) has the right to express their opinions in the form of pluses or minuses, I did not restrict users the opportunity to express opinion.
On the other hand, the rules of contribution changing depending on your votes have modified. Since we have already appeared bots, trolls and other vermin, I will not reveal details, but note that:
Just want to say that the bots usage, following the principles of "blood feuds," etc. serve as a reason for your disqualification. Do not tempt fate.
Soon, the problems coordinator, the user RAD will leave official lists of both contributions and rated, as he is active member of the Codeforces team.
I wish you high contribution

This Round was prepared with help of Rakhov Artem and Maria Belova.

While the world community of participants of programming contests is waiting with bated breath for the news about new date and place of the Final, we decided not to delay the next round and prepared some problems on the train from Petrozavodsk to Saratov. In preparation were involved Mike Mirzayanov, Artem Rakhov and Max Ivanov. Tasks were translated into English by Maria Belova.
