Beth, Have you tried what I do? I tell the students NOT to email me, but to post their questions on the FAQ discussion board. I give minimal extra credit to students who answers other students' questions. This works well. I do, however, check the FAQ every day (M-F) and answer anything or clarify anything not already answered within 24 hours. I have online courses with over 200 students in the class and my email overload has drastically reduced. Secondary questions are typically answered by the same student who answered the first question. I have also required self- and peer-evaluation using the same rubric I use to assess an assignment/project and when that happens, I have to make less comments. Again, a time saver. Hope this is helpful.
