In my first answer on ELU, I encountered difficulty in answering succinctly, due to a program built into the site that removes so called “pleasantries”.
The question concerns how to write “salutations” in emails. Naturally, my answer begins with (my perceived) correct salutation, “Dear Prof. Smith...”. However, this “Dear Prof.” is forcibly removed, and cannot be put back, even in an edit.
Obviously, I could have experimented with other ways to start the answer. Perhaps beginning with “I would write: “Dear Prof...”” would override the bug. However, I did not try, since that would involve adding unnecessary fluff in my answer, which is exactly what the program is designed to remove.
I propose either the program should be improved, or there should be some way of manually overriding it.
