Mass mail: bcc the event owner/log them

Hi,
few small things on the mass mail front end:
1. Could the event owner email be bcc'ed so they can actually see what is sent or keep a record of it?
2. Could mass mails be logged as other emails can be logged?
3. Could there be a "send preview" which sends the draft email to the author, and then they can continue editing to send the final version to the registrants (ie. one button Send Preview - sends to the auther, another button Send to Registrants which sends to all the registered users).

Cheers,
Russell.

Could we also add a 4th... set reply-to to the event owner, not the generic address?
