First things first, Codeforces blog system is awesome, however recently I had found a problem with it. I do not know what your teacher does, but my teacher is now using the Codeforces platform for teaching, as it is home to many great problems. However, some of these problems are ancient (remember that the platform is 10 years old!), and I met a problem with discussing these problems.

Problem

Currently, the discussion of problems are usually located in the announcement post or the editorial post of the contest, however, it is non-trivial to find particular discussions about one problem, and one has to scroll all the way down in search for it. But that's not the main problem.

If you have a question about a problem, the two main ways to ask it are:

• write a comment on the editorial/announcement, or
• write a blog post

Problem is, if the problem is old, they will cause the problem to appear in recent actions, imagine a Codeforces with recent actions full of questions about a round 10 years ago, that is irritating, right? It will surely attract tons of downvotes and in the end, you still do not know how to solve the problem.

Suggested solution

I suggest that the discussion system be divided into subforums (like subreddits), and a link to the subforum of a problem will appear in the Contest Materials column, subforums in concern of a problem will not show up in recent actions. Also, there should be some general forums like site affairs, contest announcements, general CP and so on.

This actually brought another advantage: if someone only cares about algorithmic blogs, he can simply navigate to the algorithm subforum and enjoy blog posts there, similar for those who only cares about ICPC news, and so on.

I hope that someone in responsible for site affairs can look into this.
