One of the things you have to watch out for if you run email announcements for any sort of organization is to always make sure to put the list of recipients in the bcc column instead of the cc column when you want them to stay confidential. There's no better way to screw up an entire business deal then to let everyone know who's in on it. It's one of the most basic, and the most damaging, mistakes you can make on a computer on a day to day basis.
This goes double if you're doing this not for a corporation but for
an international terrorist organization.
As they say, 'heads will roll', although in this case they may actually be doing so literally.
