Any registered website user may contact the listing owner by submitting a message using a listing related "Listing Send Message Form" widget.

The ability for the listing to receive messages is controlled via the listing product.

Message sender or recipient can check the message status and compose a reply in their user account panel.

An email notification is sent on a new message or a message reply submission.

Administrator moderation can be enabled for messages and replies.

Messages have "Subject" and "Message" as the system fields that appear for all products and categories. It is also possible to add message custom fields that are linked to the listing product and category.
