The comments is working for me, I entered my name, email, website and the comment itself.
Whats the problem again? Do you want to allow comments without having enter an email address at all? If this is the case I would advise against it, if I was you I would be chasing up a Wordpress API key and enabling the Akismet spam prevention plug in. Believe me, you will get spammed off the face of the planet without any form of spam prevention.
