I left a while back... What have I missed?

I joined a few years ago for school purposes. I stayed around because I would use the chats to talk to a friend between periods. (School was strict about phones, but as long as it was on the computer it was fine. 🙃) Then CDO began banning chats and such. People were trying all sorts of ways to get new chats through, some people acted like it was the end of the world, yada yada yada, I left because with the chats gone there was no reason to stay. So, here I am on an old bookmark wondering what I've missed.

P.s. I really hope I am using this correctly and am not going to intrude on the super tech peoples and their coding. Sorry if I'm not.
