I am trying to locate old friends. Is there a way to search for them? How do I search for my female friends who may have married and have a new name? Any way to do this for free?

I have found a lot of old friends through Facebook. You set up a profile, connect with the people you know, and through them you connect with those they've maintained contact, and so on. My friends and I just had a great reunion dinner, made possible because we found each other through Facebook - it was really very, very nice. Just Google Facebook, open the sight and you can post what you want from there. Very easy and free.

Classmates.com will help somewhat for free.

I agree about Facebook. Everybody in the world seems to be there.

I use Welcome to Facebook | Facebook (http://www.Facebook.com) & MySpace | Login (http://www.Myspace.com) People Search | Background Check | Reverse Cell Phone Lookup - Intelius.com (http://www.Intellius.com) could tell you where they might be now. You could always search people that would know this person.
