Sending agenda/allowing role sign up for: Guests, Prospectives and Friends/Affil

In my experience at the club level, One drawback of allowing Guest and Prospect lists in emails is that when someone is added to these lists, FTH generates a Welcome note to the guest asking them to respond within 30 days to give permission for the use of their email address.  If your guest or prospect does not respond, the email will not be included with your mailout.  

This is because of privacy and spam laws. You cannot add someones email to FTH without their opt-in.
