I am using Dropbox with 3 machines, 2 laptops and 1 desktop.
I notice that of the 3 machines, I can only access the "Desktop" of the 2 newer machines only.
It is like the oldest machine is the "Master" and the other 2 newer ones are the "Slaves".
How do I set it up so that the newest machine of the 3 is the "Master" and the other 2 older machine are the "Slaves"?
