Hello

I am looking for a plugin that does this:
- Sidebox display only when the client is connected
- Sidebox allows the holder of an account to enter from 1 to 5 email addresses
- Store in database the email addresses entered
- Generate an email with a coupon for a configurable amount as soon as an order is placed on the site by one of the addresses entered by the account holder.

This plugin is based on the principle of sponsoring a reward for the sponsor.

Thank you for your help.
