Hiding Guest Comments

[Andrew]

I have a question regarding the possibility of hiding the entire Guest
comment section.

I'd like to use an instance of Disqus where users MUST have a Disqus
profile before they can comment.

Therefore, I don't want them to even see the Guest post form - the
current set up allows data to be entered into the fields but then the
user is prompted to register by the pop up.

It is possible to hide this guest option, specifically the form
fields:

Name
Website
Email
Post as Guest button.

I assume this is possible to use javascript to hide the div element
"dsq-post-fields".

However, the div "dsq-post-footer" is context specific, as the post
button changes state depending on guest or registered users.

Any assitance would be great

Thanks
