Thank you. Is there a list of these concepts somewhere? ...I've had a little trouble searching for said list. Nevermind. I found myself wishing for Altavista then I remembered that I recently promised myself to give DDG a try: https://duckduckgo.com/?q=OP+AND+GP+AND+%28%28ORIGINAL+POST%29+OR+%28ORIGINAL+POSTER%29%29+AND+%28%28GRAND+PARENT%29+OR+%28GRANDPARENT%29%29 https://duckduckgo.com/?q=OP+AND+GP+AND+%28%28ORIGINAL+POST%... That's sufficient.
