Can someone explain how those emails ended up on google groups? If they were leaked emails, why were they taken down? This implies Josh or GAW had the control over it. I don't understand. Did they accidentally publish all their emails to google?
You bet your ass google has a copy of each and every email plus attachments now.
Didn't GAW use GMail to handle their corporate e-mail? Google probably had those e-mails all along

As to how they ended in Google Groups - there is probably a way to do it, maybe via IMAP or something. I'm wondering if whoever did this has a copy of all those e-mails.
