My students are my highest priority. But please realize that I cannot be pen pals in corresponding about homework problems or the finer points of the course, due to this repetitive strain injury. I seem to have only a limited number of keystrokes per day, and that number isn't known in advance. So a phone call (5-9884) is likely to be far more effective for this purpose. Also, sometimes a couple of days can go by when I don't have time to even look at my email. If you don't hear from me by the time you need to hear from me, please do not hesitate to contact me, the TFs, or my assistant by all the means I have given you in class.
