The main communication mechanism between the professor and students is now done with blackboard. Many of the university and student organizations now also use Facebook and/or Twitter.
A listserv is a powerful communication tool that allows members to post suggestions, announcements, or questions to a large number of people at the same time via email. When you submit a question or something that you want to share with the listserv, your submission is distributed to all of the other people on a particular listserv list.
For example, the Opportunities Listserv is used to distribute announcements about jobs, scholarships, and internships for students in the College of Science and Engineering.
