How many social networking sites are registered with?

Two only. MyLot and Yuwie. I am a member of some penpals but I am hardly on these sites...

I thought I had many but I just have MySpace, Facebook, and Yuwie. I started off with MySpace first and then I got Facebook and later on I got Yuwie because it said I could earn money from using it. I haven't seen much progress with it though. I mainly use MySpace, because I've found so many friends on it already. It's just easier that way, this way I won't have to search for my friends on the other sites. It just takes too much time for all that. I mean it already took me a while to find all the ones that I have now on MySpace.
