I need some fun appropriate site to get on?

Okay! I am totally bored and I really want some ideas of some fun websites! It can games, blogs, and or chats. The only websites that i am not allowed to get on or get an account is Face Book, MySpace, Twitter. I don't know if Skype or Flickr is safe.. Please before you recommend sites make they are safe and age appropriate!! I am only 15!! Don't answer if your going to say crap about me not allowed on those sites that I listed! My parents trust me but they don't trust those sites. So if you are going to do that you are wasting your time. Just a heads up. Thanks for any recommendations. ~Rosie!
