What defines a Team in Guru
Your Guru team is the total number of users that are billed. A team can be a whole company or a single department (e.g., sales).
Teams can segment access to content by Group by utilizing the Collections feature. When a company wishes to isolate their knowledge, multiple Collections are created to represent each segment of knowledge and the users who have access to it. Across the team, content in a Collection is accessible to all users in that Collection, with the exception of private Cards that can only be viewed by the individuals explicitly shared on the Card.
The difference between a Group and a Team in Guru
Groups allow you to divide your Guru Team into a classification of users, and those classifications of users can then be selected as Card verifiers and @mentioned in comments. Additionally, Roles are determined at the Group level by Collection. Everyone in a Group will have access to all of the content in the Collection.
