According to recent studies, teenagers generally use instant messaging and text messaging for talking friends and email for complex messages and communicating with people who can't be contacted other ways. It's likely not just the technology but also the increasing problems of irrelevant mail and spam cluttering mailboxes:

87 percent of teenagers in the US now use the Internet, and many of them prefer instant messaging to e-mail. According the report, "Teens who participated in focus groups for this study said that they view e-mail as something you use to talk to 'old people,' institutions, or to send complex instructions to large groups. When it comes to casual written conversation, particularly when talking with friends, online instant messaging is the clearly the mode of choice for today's online teens."

This is a problem for institutions that use e-mail as an official communications tool, since students often miss announcements or deadlines. Unfortunately, IM isn't great for sending out reminders with lots of specifics, such as instructions for registration. What's a college to do?

For some schools, the correct answer is: set up a MySpace page. After all, there's nothing hipper for students than being "friends" with your college registrar or school principal. The intriguing thing about this method of reaching students is that it's most often not "instant" at all; students receive messages when they log in or they visit the school's MySpace pages—the equivalent of using e-mail and a Web portal.
