`  == copyedits and refactoring talk page posts ==  Hi  Apologies, but I have to make you aware that ``fixing`` other peoples post on talk pages can be frowned upon WP:REFACTOR. While I appreciate that the ones I saw were changing from incorrect to correct grammar and spelling, the editor who's posts were changed may not appreciate it. ``Other minor fixes (correcting other user's spelling or grammar is discouraged, but fixing obvious typos is generally acceptable)``  The second point is that changing to the serial/Oxford comma seems a little strange - can you tell me why you did that in some articles?   `
