A community is a persistent space on Nooks where a group of members can gather and learn online. You can create communities for classes, office hours, social events, and much more!
If you are not currently in a room, you can create a new community with the following:
Click this button on the top nav bar

Give the community a name (e.g. "CS228 Office Hours") and click "Create"
Click "Confirm"
You should now be in your new community
