To create a group, simply click the "+ Create New Group" button (located under "My Groups" within your profile page):
On the next screen you’ll be asked to give your group a name and enter your organization.
After you save your group, a unique code will be created. Share this code with the group members (via email or other communication tool). You’ll see your newly created group under "Groups I’ve Created."
Creating a group allows you to see stats on your group members, such as rank, points, likes, comments, and collections. To view this info, just click on the "view" button beneath your group name.
