It's not impossible to find all replies - it would require basically the same kind of MySQL and PHP commands&functions as to display all your posts.
But until that time you can still get the pages that contains replies to you:
Here is a
Google search which returns all replies to you on thread 359427 (My name is Nick and I'm new here at ATS., page 1). The search term is made out of
three parts:
site:abovetopsecret.com - only return results from ATS
"reply to post by obilesk" - return all pages with replies
inurl:thread359427 - get replies from a particular thread
complete search query:
site:abovetopsecret.com "reply to post by obilesk" inurl:thread359427
Be sure to click on "repeat the search with the omitted results included".
If you leave out the inurl part, you get all replies ever made to you
as such.
Have fun!
