Visitors to the site can leave comments on any page by clicking Add Comment at the bottom of the page (your site's skin may have this link in a different place).
This feature is optional and can be controlled in Site Settings. Comments can be available to any visitor, limited to Registered Users, or disabled altogether. Individual pages can over-ride this site-wide setting to disable comments on specific pages (see Page Properties).
When a comment is created by a user that is not logged in, their IP address is used as the user name.
Editing & Deleting
Registered users and administrators can edit their own comments. Additionally, administrators can delete any comment individually. Simply log in as an administrator and look or the Delete link next to each comment.
