BCC

Have you ever received one of those jokes in the office which has been sent to everybody?
Whoever sent it has CC everyone so you can see all their names and email addresses.

STUPID and INCONSIDERATE

It’s even worse when it has been forwarded several times and there are literally hundreds of email addresses. Bad manners, and bad security.

This cartoon sums up my feelings very well.

What is worse is they don’t edit out all the email headers and other stuff, so eventually the one page joke becomes ten pages of email addresses and mail headers.
