I can't believe you've not heard of bebo - certainly one of the biggest social network sites around (multi national) if your single then it's the best because it's full of hot chicks! But it is for all ages! Certainly something worth checking out a.s.a.p - you don't know what you are missing. Bebo in my opinion is the best thing on the net (free aswell)there is loads and loads of groups you can join aswell! Similar to the way we are chattin now except it's faster. You create a profile and find old or new friends! I will give you some advice for a change and say "get yourself a bebo"
www.bebo.com just register and the rest is self explanitary! I will be your first bebo buddy if you can't find it google it ! By the way I am from Glasgow in Scotland
