Yes. It is possible in advanced search. https://www.technofino.in/community/search/?type=post. Type Technofino in "Posted by"Is it possible to see all threads posted by a user?
Eg: @TechnoFino posted cards allowed per customer and all bank email id, he posts informative threads, want to see what other he has posted...
P.S.- I then found these threads in 'Informative Threads', but not all informative threads are in informative threads, hence the query. (Eg: No of accounts in CIBIL by helloworld)
