I think that you often have something to ask or discuss advanced CP topics or some OpenCup rounds or hard problems, and it is not worth creating new codeforces blog, but current popular places with CP chats (i.e OJ chats, or discord, or some country-local chats) are too local and don't have too many people with who you can divide your discussion.
So, I come up with the idea and talked with some of my friends, that it would be cool to create telegram chat with some lower bound on the rating to join.
Now I suggest a lower bound 2600 on rating.
I. e. if you want to join the chat, and if your MAX rating is at least 2600 (so if at some point you had IGM rank), you can write me your telegram login in personal messages, and I will add you to the chat.
Of course, the lower bound may be adjusted later. And if you have suggestions about the proper places for creating this chat, you can write them in comments :) (don't worry, telegram is very convenient!)
