Sounds great with an official channel though probably best with a whole slack team and not just a channel that’s part of another team… so it got room to grow into different channels (one for each course at least) and live on for years!
Would be great if you could invite everyone that signed up to the slack team as well =) Happy to moderate when I can though I don’t think there will be much need if only paying students are invited to it!
Cheers!
