Uploaded files are accessible through any browser. Privately share and collaborate with certain people or share something publicly to your network. Post large files to get all the feedback in one place.
Anyone can see what you post on the “Chatter” tab, your profile page, and in a public group. However, posts you make on a private group or records are only visible to those who have access to that record.
To change Chatter email notifications, navigate to Setup > Personal Setup > My Chatter Settings > Chatter Email Settings. Control the frequency of notifications for your private and public groups on that page.
Using status updates, you can quickly post a file, link, or update that all of your followers will see in their Chatter feeds. Other people in your company can then comment on your post and engage in a conversation right in the feed.
