VirtualCallboard is capable of managing multiple companies (groups of collaborators working on the same project) as well as multiple productions per company. VirtalCallboard silos the information in such a way that only users who are members of a specific company will see the relevant information about that project.
This powerful implementation allows you to use one VirtualCallboard account to manage an entire season of productions, whether you use the same group of collaborators or an entirely different group for each project.
