Astronomers need help

Some time ago I wrote about computers needing human assistance for certain tasks, like recognizing images or understanding text.
This time astronomers need human intelligence to assign pictures of distant galaxies to a few categories. This is another task, that's trivial for human but immensely complex and error prone for computers.
The project is called Galaxy Zoo and its concept is simple :
A picture of a galaxy is shown to you and you have to decide which category it belongs to.
This is how you get started : After registration, you get a small tutorial explaining the different types of galaxies. After the tutorial you have to do a small test where you get 15 pictures of galaxies and you have to decide which category they belong to. When you get 8 out of 15 correct, you can start sorting new galaxies.
