Hi
Have there any good site feedback mod for x cart?
My requirements are -
a) I want to display a good site feedback form when a visitor/customer cross the browser or leave the page with some fields like name, email id, phone no so and so.
b) When a customer buys something and after completion then this feedback form will open to give him/her feedback.

This name and email id must be added in the database for future use to send them newsletter.
