This a great add-on!! When I started using Tbird I just assumed all e-mail addresses in a group would be BCC'd as they are in many other email programs such as Gmail and Outlook...not so!! It's imparative to keep my group e-mail addresses private, so this resolved that issue.

Thanks so much for this!!
