Thanks Laura. To clarify further, my colleagues and external users can edit and collaborate in my premium content (ie. gantt charts) that I create without all of them subscribing to a premium subscription? Thanks in advance for the clarification and I just want to make sure that premium subscription is needed for the project managers only who create the Gantt chart, but not the users, collobrator or contributors who access or edit gantt chart. It would be way too expensive if all people who see, touch, or edit gantt chart need a premium license.
