The Home tab is made up of three sections: header, main feed, and tab bar.
The header is where you'll find your Cocoon's name and a display of the people who are in it. People who are online at this moment (viewing the Cocoon right now) will appear on the left, with a small dot next to their photo. People who are offline (not viewing the Cocoon) will appear greyed out, to the right.
The main feed is where all of the updates (manual and automatic) will appear in a chronological list. The newest updates appear at the bottom, similar to how a message thread is organized. All members of the Cocoon can post and view all of the content in the Cocoon.
The tab bar is is used to navigate to the different spaces of the Cocoon. Each of these tabs has its own section in this FAQ.
