College students are relying on the Internet to make connections with other people every day. As the Internet has developed and grown, so have the capabilities for interaction. Social networking sites, a group of Web sites that provide people with the opportunity to create an online profile and to share that profile with others, are a part of college students' regular daily lives. With this new technology, questions about ethical use and the lines of what is private and what is not have become so blurry and misunderstood that students can find themselves involved in situations that are less than desirable. Little empirical research has been related to technology and privacy issues, although numerous anecdotal and opinion articles explain social networking sites and the negative actions taken by individuals on these sites. The topic of social networking sites has gathered increasing amounts of attention from student affairs professionals. Indeed, many formal and informal conversations at national conferences as well as personal interactions between colleagues have considered how best to deal with them. In this article, the authors provide a beginner's guide to help professionals understand privacy rights related to the use of social networking sites and the ethical dilemmas related to their use in work in student affairs.
