Drop Down List of Names Directs Submit Button to Specific Person Email

This has been a fun week for me in LiveCycle, and I bring yet another question to the Experts here:

I have a Form that has a drop down list with about 15 different names.

This Form will need a Submit Button that will automatically go to the email of the person select from the drop down.

Can anyone provide a coding example?

So far I found post by Stephen Cameron online: http://forms.stefcameron.com/2008/08/28/submitting-form-data-by-email/

But it is old and am wondering if this is still accurate, or is there a different (or simplier) method I should be doing?

I'm using LiveCycle Designer ES4 if it makes any difference.

Have a great weekend and as always... Thank You for Any Assistance!
