I am desiring the effects of your second option and thank you for confirming that it is working by default. That's what I thought should happen, but I mis-understood GreatMarko's quote of 'Changes (additions/modifications/deletions). It seems that you are calling the receiving machine (the node or peer) a 'read-only' or 'read & write' based on what is does to OTHER machines rather than what it does to itself - and these settings are set on the machine that is sharing the files. Am I correct in this thinking? I find that the explanation here http://help.getsync.com/customer/portal/articles/1627117-guide-to-ui-share-window- explains it the same way. As a side note, if my understanding is correct, a 'read-only node' could actually be both a read-only node AND a read-write node based on the share's settings of the other machine. Thanks! I can't say that is what I'm looking for yet, but I'll have a look at that topic.
