Very nice feature but if you select to send to a specific person it is hard to use:
a) as page gets very long as all users are shown as radio buttons
b) no way to search for a user
c) if it also listed the name of the Listing/Business next to the user it would help
d) username is often very short and unhelpful, so also showing First and Last name would be useful, even if that was just when you hover over the name
