If your subscription plan supports teams, you can setup and manage your team by clicking "Team" in the main menu to the left.

The Teams list will show you all of the teams you are a member of (if you've been invited to join other VA's teams), including your own team.

When you first visit the Team page, you'll be prompted to setup your team by giving it a name. 

Once your team card appears with its new name, you can select it and start inviting members.
