When a user makes a comment on an anchor post, the system will create a new Cacbot conversation in the background, record the conversation on that new CPT, and display the comment thread on the anchor post in the frontend. This allows many users to chat with a particular Cacbot, on a particular URL.
You can designate any post type as an anchor post. This allows you to enable a Cacbot on any WordPress post or page.
To enable an anchor post, set the custom field post meta _cacbot_anchor_post to the string true.
