Person who sends the update should get ccd on email notifications to those they sent the update to

[#1]

Currently, when I post an update to a project, I can tag someone in a directed update.

I wish there was a way to get ccd on the WF email notification to the people I included in a directed update so I know who the email was sent to. That way, if someone who turned off their email notifications SHOULD have gotten the update, but didn't, I would see that they were NOT included in the email update.

Currently there is no receipt that an update was sent to someone, and if WF is not tracking the recipients of each update (response or new), there is no record that the notification was sent.
