I don't see the option to share my photos online, or it's greyed out. How do I fix it?

After you dance a song, you should see the option to Share Photos Online before you land back in the song list. If you don't see this option, it means that your security settings for the gamer profile you are using are set to not allow online interaction. You'll need to adjust three options to allow photo sharing: Kinect Sharing, Member Content, and Social Network Sharing. Currently these options can be found under Online Settings.
