Have you used reunion.com?

I prefer Classmates you can look to see who is on the list there without having to pay. You can't send them a message or anything unless you pay, but a paid member can send a non paying member a message. Reunion makes you pay just to see if someone is looking for you. I don't like that. Have a great day!

I have never used this site before, but a friend of mine in the USA did, and she liked it. Another friend of mine in Russia used it and old me it was a great site.
