Email, in particular, gives students quick and timely access to faculty and the program, and the program and faculty with similar access to students.
Email provides instant access.
Job and internship postings on the email give an advantage to students in either of these endeavors as well. Incoming students should automatically be assigned an email account. There are plenty of labs on campus with access from early in the morning until late in the evening and on weekends, or you can access from home with a pc and a modem. Although the law is somewhat murky, note that email from or to UWM may be subject to public disclosure. Some of this is easy.
