I periodically send out jokes to a list of people who don't know each other, and who don't want their e-mails revealed, so I BCC: all the addresses to keep everyone happy. But the BCC: Option is missing from Thunderbird 1.0. I start an e-mail, click on Contacts and only TO: and CC: are available. Can I add the BCC: button to that screen, or am I stuck with manually changing the To: or CC: to BCC: after adding the recipients' names to the e-mail?
