Often an email exchange can be derailed by simple formatting or punctuation issues. For example, using all caps can imply anger or frustration, when mere emphasis was required. Why not simply use underlining instead? Proper salutations in emails can set the best initial tone, e.g., "Dear Professor Schmitt" or "Dear Samuel." With today's prevalent use of texting and online chatting, basic rules of decorum and manners are being lost. Proper tone is essential, and students and instructors must be careful to explore not only the content of their exchanges, but also their mode and pattern of delivery.
