I’m always surprised when this window pops up when an exchange with another poster extends beyond a couple of comments.
Isn’t this a discussion forum? Aren’t we sharing not just with one, but with everyone here?
Sometimes peeps get off track / OT and end up having a longer conversation. It happens all the time. The popup suggesting to take that exchange into a private realm almost comes across as a reprimand 
Just one lowly user’s opinion, of course.
