Public communication (such as the communication taking place in the Questions and Answers discussion forum) is meant to benefit the entire class. Public matters include asking clarification or assistance with course readings or assignments, asking instructor and/or peer input on course-related matters, contributing useful resources, etc.

Personal communication only benefits the student in question. Personal matters include difficulties submitting assignments or accessing tests and quizzes, reasonable late-submission arrangements, disability accommodation requirements, questions stemming from assignment grades and/or feedback, etc. Such matters should be discussed only with your instructor.
