Jeez Ray, sorry my happy dance and gloating opened an old wound. There are many people that I think about often, wondering where the hell they disappeared to. I get a bit of spare thyme at work, late at night and have found a few ways to track people down, all you need is the name. You should track those 3 down and make contact, 20 years changes things. I just spent an enjoyable weekend with an old friend that I fell out with about 10 years ago. He is as stubborn as me. We'll see how far the reconciliation goes. You have nothing to lose by making contact and everything to gain. Do it.
PS, none of what I do is illegal, there are a few websites that people happily register on. Some not so happily. Online phonebooks and a website called schoolfriends.com.au are a good start. It lists people in Aus and NZ. I think there may be one in England.
