FriendsReunited, though I don't know if it works outside the UK.
The will to neither strive nor cry,
The power to feel with others give.
Calm, calm me more; nor let me die
Before I have begun to live.

-Matthew Arnold

Maybe try MySpace?

You can search people's names on it, so you could find your old friends I guess. But then it all depends whether they have MySpace or not, but I guess that applies to ANY site you try so... go with MySpace.
