Why doesn't codeforces have the feature of separated discussion page for all the contest problems.After the contest sometimes it becomes too hard to solve many problems.Though the editorials are provided but sometimes we also can't understand the editorial properly.Sometimes we have lots of confusions with the problem description and the logic and algorithm to solve that problem.So that would be really great if codeforces provide the feature for discussing the specific problems in separated discussion pages/forums where all the participants will be able discuss on that problem.Besides, that will be also helpful for other participants who will try to solve those problems in future.Because they can then see the previous discussions on any problem and clarify their confusions.Of course i like all the codeforces features very much but it's just my own opinion as i feel it most of the times :)
