I've noticed that when I receive a reply from a nitpicker, that it comes from the nitpicker's own email address, rather than "email@example.com." When we try our successive assignment attempts, should we send it again to the generic "firstname.lastname@example.org" address, or reply to the email address of that nitpicker who first critiqued the assignment?
For the same assignment, you can reply to the person that nitpicked you, but when you start a new assignment, send it to email@example.com again. The nitpickers will stay with a student on a particular assignment, but when new assignments come up, you may get a new nitpicker. Bill
