Yeah, i did the same. But definitely not the best solution. That's why i opened this section. A simple "Send" button with function of notify the receiver about new message in site's inbox, and the message itself to be sent only in the member's mailbox should be just fine. Cause why so much bother for the user to select so many things like "notify to site, personal email, notify by email" is very confusing for the member.

Just send notification that he has a new message on his see more account. Anyone S.O.S!? :)
