What is the activity feed?
The activity feed facilitates workspace collaboration by displaying users’ real-time activities in Whispir and any discussions about those activities. The types of activities you can view include who has logged in and when, who has sent messages, who has created a new template or distribution list and so on.
You view the activity feed in the Latest activity sidebar. To open it click 
on the User Options toolbar.
Note: You might not have access to the Latest activity sidebar. It depends on your Whispir role and how the company administrator has configured this feature.
