This is a HACK and not a properly written plugin. We strongly discourage using this. This page is only kept here for reference.
What you get with this is a customizable (via the back office) plain text field that your visitors will have to fill in before they can leave a comment. Registered bloggers are exempt from the test, as are those who've successfully left a comment already. You will be able to customize the test and answer and rejection text in your back office.
