GroupMe is the official method of communication within CCS and the 2303 Sheridan dorm, alongside emails. As a resident member, you should join both group chats to avoid missing any important announcements.
To prevent spam and bots, links are not (and should not be) posted publicly. You should find QR codes for joining on posters around the building. In case you are not able to find the correct ones, please contact the exec board.
