I am asking this because there were a few occasions when I felt an urgent need to edit a person's solution that had been written rather poorly (e.g. using non-standard abbreviations or committing really gross spelling errors). In the end, after making the necessary edit, I received a rather rude response from the person.
I would like to know, is it an unspoken rule that one communicates privately with the person about what corrections should be made before effecting any edits?
