Round table

Do you specifically want a chat on HW to be implemented programmatically? For now, try creating one on VK; almost everyone has an account there, right? Those who want to join and chat can do so. This will give you a better understanding of the target audience. P.S. There's a user named Vlad who keeps asking who should be given admin rights for the Heroesworld group on VK, etc. If the idea is interesting, you can join, create a chat, and people can add themselves.
