I am writing to get your help in order to avoid posting a duplicate question.
I have the same problem reported here: Using “and” instead of ampersand in natbib in-text citations (“\citet”)
The answers given are not satisfactory to me. The post is not solved (i.e., no answer has been selected by the OP as the right one, even when he himself has posted a solution for his problem).
So, my question is: how can I post my concerns to the questions given and add more information about the issue I need to be solved?
(1) Should I edit the initial question of the OP (by adding an 'EDIT' section)? This is what I would do if I were the OP and wanted to clarify why the answers given do not solve my problem.
(2) Should I, instead, add one comment in the question(s) given for now?
