Office Hours:

* Please add yourself to the cs555 mailing list
... by typing "mailer add me to cs555" and hitting RETURN on a CS machine
(if you don't have a CS account just drop an email note to a TA asking to
be added to the list).
* When sending me email please include "CS 555" in the subject ...
... to guarantee priority processing of your email; I am flooded with
non-spam email every day, most of which is slow-processed unless
it includes something that makes me treat it with priority (like "CS 555"
in the subject, or email from someone with whom I collaborate, etc).
I generally prefer to answer questions about the class in person, either
during my office hours or in the classroom, because (i) the communication
bandwidth is better than email; (ii) I have trouble typing due to an RSI
problem with my hands; and (iii) others may benefit from the answer.
