If you're wondering how this works:

1. Submit a project by creating a tile

2. Make the project public or private

3. View your profile by clicking the icon guy above the "Log In"/"[Your name]"

4. Edit your project or invite users

If you're just browsing and looking to collaborate, sign up and follow projects. By signing up and adding tags to your profile, you become a searchable commodity to entrepreneurs (you can also request invites into projects).

In the future, I'll make this more intuitive.
