As roles in projects are different, some will "only" have to fulfill some tasks on cards, other are the project owner and as the board owner they need a broader view to lead the project. Question: can basic and business users work together? Can a business user give a task to a basic user? And can the basic user then comment on it? And if so: will the basic user still be free of charge?
Or will the company be charged for anybody who fulfils a task?
How about external parties such as agencys - can we collaborate with a trello board?
Thanks!
