Thanks for your reply dear
What I mean is that the comment is seen only by the owner of the list, the person who commented on the list, and the supervisor of the site.
It is also a private message between the two parties only.
I want to amend this
<?php if( osc_reg_user_post_comments () && osc_is_web_user_logged_in() || !osc_reg_user_post_comments() ) { ?>
How can it be modified so that the content is seen only by the owner of the list and the person who commented on the list and the supervisor of the site.
