I have an idea where you don't show the add a comment link unless the person is logged into the Wordpress blog already.. or they need to log in in order to comment.

I think it would require some wordpress code in the zenphoto photo pages.

I don't know how to do this. Would anybody out there have an idea if this might be possible?

I'll keep researching and will post my comments once I find some answers.

Thanks,

Charles
