If you wanted to invite say 1,000 people to take a look at a Real Estate property like:

And you use the invite feature.........I got an internal Error but also received several e-mails myself as i put my e-mail address in the invite list.
Hmm you see the question in my mind......... Is there a outgoing log and if so where is it if not how would a person know who got the e-mail and who didn't?
