Fun Websites for people over 13?

[Rawr!]

My 13th birthday was yesterday, and just as something fun to do on my birthday week I wanted to sign up for some sites that require you to be over 13 just so I could put in my real birthdate and still be allowed to join. But I realized that most major websites I'm already signed up for with a fake birthday. This is kind of annoying because I really wanted to do this!! Does anyone know fun websites besides:
Facebook, Twitter, Blogger, Tumblr, Youtube?

I'm a girl if that helps
