If someone is invited as a Guest on one board (for editing access), and set as an Observer on another board, are they then considered a billable multi-board Guest? (Even though they're technically only a "Guest" on one board and "Observer" status is supposed to be free?)
Also, if someone is merely an Observer on multiple boards, I assume they wouldn't be considered billable because "Observers" aren't billable. But I want to confirm that they aren't considered "multi-board Guests".
