Using ClassiPress 4.x you can view all the customer comments left on advertisements from the admin dashboard.
Locating the Comments Section
All Comments can be found by clicking on the Comments menu from the WP dashboard.
Once you click on this menu you will see all the comments that have been posted on any ad within your site. You can see details of the user who commented, what they commented, which ad their comment was posted on and when their comment was posted.
From the comments menu you have the ability to delete, edit, approve and unapprove comments made by users on your website. If there are many comments on your site, you can use the Search Comments tool to locate the comment in question.
