* Final exam is Tuesday, May 5, 2009, 7:00pm-9:00pm in BRNG 2290

* When sending me email please include "CS 381" 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 381"
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.

* Please add yourself to the cs381 mailing list

 ... by typing "mailer add me to cs381" and hitting RETURN on a CS machine
(if you don't have a CS account just drop me an email note and I'll add you 
to the list).  Please use your Purdue email address for this list and for 
all emails about this class.
