I'm sorry I don't know whats wrong there... I never had problems with that on my site. Here are my configuration settings:

- allow comments -> yes
- anonym comments -> no
- allow BBcode -> yes
- Spam protection -> no captchasystem

It seems like the cookbook does not recognize that you are logged in. Maybe somethings wrong with the installation? Have you installed the servicepack?

I've seen this topic and i have the same problem with comments. I'm logged, but i've no button to submit my comments. I've tested it in admin and in registered user, it do the same thing.
Does anyone has solve this problem ?
