like old friends you went to high school with

thats free
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

Arguments are to be avoided; they are always vulgar and often convincing.
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.
