You might want to consider letting your users know that even if they 
send e-mail out with BCC: the header will be included, so anyone who 
looks at the message source will see who the recipients were. This way, 
either they must send each message individually (some MUA's will let you 
do this) or risk others knowing who they BCC:'d the message to.
