How do I create a team?
On the top right of the window, there is a "+" button. Click it and choose "Team".
The system will want to know the name and a short description for the team. Fill the fields and click "Create team".
In that team, you can create several projects to contain your user studies. A team is also a rule for visibility: Anyone who is a member of the same team can see the projects, studies, and all the other things that the team has created.
