You can find old friends you went to school with on Facebook.com. Complete registration to begin building your user profile. You can create your profile with details such as past education and location. Once you finish updating your profile, you can see names and pictures of others who attended and graduated from your school.
If your old friends did not go to school at the same location, you can quickly search for them by entering the first and last name in the search box. Facebook also gives the option to search for the person in a particular area to help narrow down the results. Pictures are also available in the search result to help you quickly pinpoint the right person you are looking for rather than searching through text.
The career social network LinkedIn allows registered users the ability to find colleagues and associates for networking purposes. If you know a current or past employer of a friend, find that friend by typing the firm's name in the search box. The friend appears if he or she lists that company on his or her profile. Finally, Twitter is also helpful for finding old friends. Enter the username in the search box.Learn more about Social Media
