On the left side menu, click on "Admin" and then on "Teams". You will be redirected to the team management page of Runrun.it.
First, let's go through the process of creating a new team:
Click "+Create". A new field will appear to you. Enter the name of the team, and click "create". It will open the window to create the new team.
First you must choose the team leader. If you don't do that, you will be automatically the team leader. Then, include members who will also be part of it. Click "Save" and you're done.
To change the members of a team, choose the team that you want to make changes in at Runrun.it team management page, and click "Edit". Make any necessary changes and click on "Save."
