Email completion of course to 2 email addresses

Hi there,

I need to set up an action in a single course that will send completion emails to 2 separate user groups (depending on who is attempting it). These will be two different email addresses and i can't use the LMS to do it.

I've had the idea of creating some user fields to get the content in but:

1) how do i set up the fields correctly so the user can enter the information

2) how do i get that information sent to the right email address

The course isn't a % style course; it's either completed or not so there's no scoring needing to be sent.

Any help would be greatly appreciated.
