Step One: Sign in to Facebook using your email address and password. If you registered with your school address, you must follow the directions provided to authenticate your college network choice.
Step Two: Click on the "My Accounts" link and choose the "Networks" tab. You should see a list of networks you already belong to on this page. If you are a new user, you will be able to sign up for new networks from your home page, so you can skip this step.
Step Three: Fill in the college network form with a valid email address. You may use a student or alumni address from an approved school.
Step Four: Check your email. A confirmation email should arrive with directions on how to authenticate your college email address. Follow the link in the email to officially join your college's network.
Step Five: Log back in to Facebook to start browsing your newly added college network. You may also want to consider changing how your old college buddies view your profile. You can set different privacy settings for each network you join.
