The Team Activity page displays a running feed of every update performed by a member of your team.
Why do I see only this tab?
This tab, by default, will be shown to every user in Kapta. Managers (defined as those users who have people reporting to them) will have the other tabs displayed under the "My Team" view.
Who's on my team?
I can quickly see who else is on my team by clicking the "Home" link in the header, then choosing the "Updates" tab. This will show me a listing of what my team name is called, and who's on my team:
Collaborating with my Team
Underneath many of the feed items on this page is the "Add Note" link. Clicking this will allow me to send a note to my teammate in real time. Simply click the link, add your note and click Post.
