The Internet has made it exceedingly easy to get in touch with those with whom you've lost touch. Whether you haven't spoken to your long lost roommate since your college years or you simply feel like you've been out of touch with your social circle, the Internet can put you back in contact quickly. Social networking websites have made reconnecting with old friends not just easy but also popular. Certain sites also target specific markets, such as old classmates who want to reach out to each other.
Contact a current or old mutual friend. Sometimes the best road to contacting a specific person from your past is to contact another person from your past. The mutual friend may know exactly how to get in touch with the person you seek, or she could help you out and search for the person as well.
Sign up with your college alumni website. If you're looking for someone you went to college with, you may be able to find them if you're both listed on the school's alumni network. You also can see if the old friend has signed up with websites that focus on former high school classmates.
Search for the person on a social-networking site or a website designed for contacting people. Many people have MySpace or Facebook profiles, and these sites provide a way to message them directly.
Set up a time and place to meet if you're both willing and able to come together. Chat about the past that you shared and your current lives. You may easily fall back into your old friendship, or it may feel less natural than you expected.
