The Nag relaunches this week, with a new look, new features and a new push to harness 'online crowd power' to help solve the world's ecological and ethical problems. The new 'Get it Off Your Chest' section is where you can rant about your green frustrations, while the 'Suggest Solutions' section does what it says on the tin (err... actually YOU and other users do what it says on the tin). And the 'Do Something' section lists actions you can add to your To-Do list and helpful hints to green up your day, often without feeling even a twinge of sacrifice.
