hi,
emails can be sent "to" somebody, "cc" (carbon copy, no action required from recipient), and "bcc" (blind carbon copy, the recipient does not see who got the mail as a blind carbon copy).
there is two ways of using bcc, one is considered quite rude, and one i believe it was originally invented for:
1. the rude way i want to write to a person, and put you on bcc, so you would get a copy of the email without the recipient is knowing of it. this is considered _very_ rude, even dishonest, by quite a number of people. please put persons openly on cc, and maybe even mention why you put them there.
2. the good way i want to invite 50 person to a party, and i do not want to disclose all the email addresses to everybody. so i put myself in to, and everybody else in bcc. its clear for the recipient that he was on bcc, and everybody else as well. so "bcc" is actually like "to" - the recipient is required to do something.

ps: sorry to write off topic to this mailing list, but i got a couple of emails bcc in the last months, and it is probably better to state this openly.
