When you sign up for a Premium Course, we automatically invite you to a Slack channel just for this course, so you and the other students can talk about assignments, programming, and anything else that comes up. We can only send out so many invites at once, so you might not get your invitation right away.
Invites come from
firstname.lastname@example.org so make sure to check your spam and trash folders if you don't see it in your inbox.
From there, make sure you sign up for a Slack account right away so you can get started!
