I teach online and have the same issue. In my case I could have students anywhere around the globe. We also have a significant number of students in the military who have crazy schedules. While I do get a few students who visit during scheduled "office hours", most of my students end up e-mailing their questions. It is not as efficient, but at least I'm able to help all the students who request help.
Brian,
Good point. We may not reach all students, but those who want help know how to reach us especially if we post our office hours.
