5. When corresponding with your professor, please use an email address that sounds reasonably mature. SUPERHOTCHICK111 may produce an undesirable impression.
6. Professors may not respond immediately to your emails. This should not send you into a panic. Or into a snit, for that matter.

8. Do not ask your professor "Did I miss anything?" or "Will I miss anything?" or "Is there something important we're going to talk about?" Just don't.
