Communities
So that students can connect with classmates via platforms on which they’re already spending (too much!) time, CS50 has official communities on Discord, Ed, Facebook, Gitter, Instagram, LinkedIn, Quora, Reddit, Slack, Snapchat, SoundCloud, Stack Exchange, TikTok, Twitter, and YouTube.
If not already a user of any of those, allow us to suggest that you start with Ed!
