Free and Pro accounts can have an unlimited number of single-team guests. Only Pro organizations are allowed multi-team guests (guests that belong to more than one team).
Admins and User Managers can manage guests by clicking Settings (gear icon) and selecting People. Once on the People screen, select the "Guests" tab.
Please keep in mind that a guest who belongs to only one team is free and does not require a license. A guest will need a licensed seat to become a member of more than one team. Admins and user managers can manage user membership from the People screen and easily view which guests are consuming licenses.
