A Team is essentially a grouping of internal users, such as Teammates, Project Managers, and Freelancers. Many times when working on Projects, you will be assigning the same group of users to the same types of Projects. For example, if the Project is a new website, you know that Bob from the art department, Shelly from programming, and Project Manager Tim will all be involved. By creating a Team, you can easily group these users together, allowing you to assign all of them to a Project at one time, without the need to assign them separately.
