Drupal five star module

I have a restaurant site where I display dish pages; customers can rate every dish in my restaurant.

I use Drupal 7,Fivestar and Voting API. I can rate every dish, but what I want is a window where a customer who gave the maximum vote to a dish can write a "thank you" message to the chef.

Can I do it with Fivestar? Do you have any suggestions开发者_高级运维?

If you are using Drupal 6, Fivestar comes with "Fivestar Comments" that displays a rating widget when a user posts a comment; the rating of the comment will affect its parent content.

This is the best you can do with the Fivestar module, and without to write any custom code.
