Reviews in Directory Plugin

Hi,

I am trying to setup your directory plugin for a business association site. I see in your screen shots that you have reviews as a custom field. Can you explain how the reviews can be added? I've created a post type for the reviews and a bunch of custom fields for the directory listings. Not exactly sure how the reviews would connect to the specific business being reviewed. It would be really awesome if you guys could provide a working demo of this plugin.

Thanks,

John
