Require login to post review

I was testing the site as a logged out user today and discovered that I can review a listing without logging in and adding an email and website. I really need people to be logged in to review otherwise we’ll be spammed by all sorts. I can’t see anywhere in the functions template to change it. How can I change that form to a login or register button?

Also on the profile page, the link in the posted review that says “more” in lower case to open the addition ratings – I wanted to change the text for that, found

<div class="overall-more-rating"><a href="javascript:void(0)"><?php _e('SEE MORE', 'geodir_reviewratings');?></a></div>

in the file geodir_reviewrating_template_functions.php and changed it there and it works in the parent, but it does not work if I copy to the child theme. Does this have to stay in the module files? Is there another way to change that text as it was a week before I even saw it – sure site users will miss it. I’m assuming that the style that hides the text is in the JS. Didn’t find that either.
