I still am not having any luck. I put by:John Robinson in the box and hit go. All his THREADS he has posted came up. So I clicked on this one and then in the upper left I saw, ARTICLES, COMMENTS, SEARCH. Is this where you mean to click on comments? If so when I did that it just went to LASTEST threads posted.
Go to by:johnrobinson again
when you get there, do NOT click on a thread
above the threads, there will be choices
Articles Activity Comments Full
They are all clickable
click on “comments” and you will see his comments
Now be careful, don't click on a thread!
