Removed block on /skins .... single.main.php to stop feedback block for non registered users: !isset($current_User) as it would block comments as well as the feedback form. ( in calstock.org.uk only)

In calstock.org.uk and rogerlovjoy.net, blocked the feedback form in /skins .... _item_feedback.inc.php
Insert

if (!isset($current_User) )
unset($params['disp_comment_form'])
