For my students, during office (9am-11am MWF in the large computer lab in ACAD) and E-Office hours (9pm-11pm W) I have come up with the following nifty ways to contact me:

Yahoo! Messenger: professorwend
Google Talk: professorwend@gmail.com
AIM: professorwend

The really cool news: I now have a voicemail/office phone number. I can be reached during office/e-office hours at 609-836-0641. During other hours you will be prompted to leave a voicemail for me.
