…The title says it all 
I would like to know if I can talk to User #1 using Private Message and quote posts by User #2 without them being notified or get the ability to read the PM between User #1 and myself.
##Results
If User #1 & User #2 are sending each other Private messages, and quote User #3’s post, User #3 will NOT be notified
If User #1 & User #2 are sending each other Private messages, and mentions @User#3, User #3 will NOT be notified
Lets test it.
Sweet! Anyone else want to join in…we will need a 3rd person.
Someone send @wortime a message 
, and quote one of my replies. Ill see if I get a notification
Reply back once done.
Done check if you got a notification.
Test is done and done.
Awesome! Thanks @YungBuck and @wortime for taking the time to test this.
Its official! You are NOT notified when someone mentions your post in a Private Message (If you are not included in the private message).
While you both are here, can you also try to see if mentioning @BrandonBerner in the private message notifies me? Let me know once you have done it.
Mentioned in test
Great! Thanks for doing that.
I was NOT notified that you mentioned me in the Private Message.
Thats great news! Private Messaging is in fact…Private
If anyone is wondering why on earth I wanted to figure this out, its because I want to talk behind all of your backs!
…just kidding!
I want to quote all the complements I have received on the forum by sending myself a PM. They are to nice to just read once
I will also be PM myself quotes of others, and keep private notes on them for future referencing (kind of like the Bookmark feature + adding my own notes/ideas).
Lastly, I want to pre-write out future topics (like a draft) and once complete post them publicly
I dident want to bother everyone by mentioning your posts all day long every day.
good to hear, that’s how it should have work indeed.
it has started
