Office hours are 4 p.m. to 5 p.m. (Central Time) on Tuesdays, when you can find me either in the appropriate LEEP chat room or as jmu2m on AIM. For class-related business, office hours are the preferred mode of communication. You can also make an appointment to chat: have a look at my calendar, and if you see an open time that works for you, contact Dorlene Clark (email@example.com) to schedule something.
Outside of office hours, email is the best way to reach me (firstname.lastname@example.org) and you should expect 24-hour turnaround. If you flag the email in the subject-line as EMERGENCY I will respond sooner if possible. In the unlikely event that I take more than 24 hours, my Inbox Desperation Index may suggest a reason. If for some reason email won't do, you can find other means of contact here, but please don't call on the phone before 8 a.m. or after 9 p.m..
