As for email, I check my email every evening.
In the event that you experience difficulty in one of my courses, please email me for an appointment and we will discuss your problem and its solution.
In other words, do not contact me at the end of semester and tell me that you are having a problem with the course.
At that point, it's too late.
My goal is to help you learn and I can't help you if you don't tell me what you don't understand.
Make sure when you send me an email, you address the Subject as 'REL-374-01 & last name' or 'SOC-393-02 & last name,' for example 'REL-374-01 Smith' or 'SOC-393-02 Smith,' respectively.
Addressing the subject correctly will give your message a very good chance getting past my ferocious junk mail filter.
For non-students, choose one of the following options:
Soc - Request
Soc - General comment
Rel - Request
Rel - General comment
P.S. To foster engaging classroom discussions, I encourage you to read the following:
