How does one make a source folder project to be "public" in ProjectLocker?

When creating a new project in ProjectLocker, by default it makes the project private, and you have to explicitly add people to the project. What if you simply want to make the project public. Seems like you should be able to do it开发者_StackOverflow社区, but the UI is unclear.

All ProjectLocker repositories are private at this time. ProjectLcoker does not have a notion of a public project that people can access.
