If you would like to send and receive e-mails from people outside your class, as well as those in the class, use a public e-mail list. Public lists can be useful teaching tools if students are responding to a debated issue through their writing. Start your own class group, or have students join a group that already exists. Involvement with outside groups will help students access information on their issue and learn more about local events.
