Are you aware that the number of the post to which you are responding shows up in the info line just beneath your name?
It’s actually under the AM or PM time stamp in that line.
Probably not. After working during the day, I have about 10-20 research organization emails to answer, plus those of civic groups, friends, and those from my work colleagues, plus an author, family/lawyers, etc.
But I like to personalize my reply with names and numbers for those who want to do a quick link to the comment referenced.
