How do I publish my projects?

1) go here and paste in your code
https://www.khanacademy.org/computer-programming/new/pjs

2) hit save

3) in less than ten minutes, people can view your program in the recents list. People can then vote it up and interact with your program

Note: if you have a child account (you're under 13) your programs will not appear

Contrary to this, is there a way to have your program not appear publicly? Additionally, can we see if our own project has been submitted?
