As for a "personal" email address, I'm sure it's bad enough to receive and reply to hundreds of emails a day when you're getting paid for it. But it really would suck to have to do it for free. So I wouldn't hold your breath waiting for him to let that bit of information get out.

I'm sure when they're ready, they'll let us all know.
