Good morning, Wei. A couple of things. I received your latest paper and will work on it after I finish the other, but I doubt it can be done tonight. Hopefully, tomorrow morning. Also, you cannot send a paper as a three-day job and expect it back in one, or even two. The speed of return determines the rate. As for commas, they are not counted as words by the Microsoft program; they are counted as characters. So you should not delete them from the word count.
