CF is a nice platform for Competitive Coding, everyone knows that, but once in a blue moon, there comes a contest which is good otherwie except for one or two silly errors from the Problemsetter's side. And due to this the round becomes unrated. This comes in as a boon to many but at the same time, many contestants feel sorry for themselves who were doing well in the round and ready to get a good positive delta but WHAM!!!!! The Round is unrated. I propose through this blog that in such cases, participant should have an option whether he/she wants the round to be rated for himself/herself or not. And then in the end, accordingly, the result is compiled (seperately for rated and unrated contestants). If this is possible, I think, it would be a really great feature to CF. Thanks. Any views on this are welcome. UPDATE : This option will be unlocked if and only if there is some error on the problemsetter's side.
