Sending invitation codes?

Hello,
I’d like to know if this plugin supports any way to send the invitation codes to future registered users. As the users are still not registered and we don’t have their email addresses, one way coul be a link on the site (frontend) saying “Request an Invitation” which leads the user to a form where he/she submits his/her email address, where the code is sent to (in the mail body there’ll be the code and a link to a registration form where to submit the code and additional fields).

Well, I think I’ll have to code this process. Any hints on how to use this plugin to achieve the flow I explained?
