Creating a Squad is a simple, two step process. First, add the name and email address of players who will be part of the Squad. Go to Create Squads in the left navigation, and click Add Player in the upper right corner. Once players are added to your host portal, they can be added to any Squad.
Step two is to create the Squad. Go to Create Squads in the left navigation, select the My Squads option, and click the Add New Squad button in the upper right. There you will give your Squad a name, upload a Squad image, and select Squad members from the Players that were added to your portal. Now that your Squad is created, you can invite the Squad to join Challenges.
