Fcc
In Eudora and perhaps other e-mail facilities, you'll see the abbreviations "Fcc" and "Bcc". "Fcc" is the same as "cc" or carbon copy - that is, send a copy of the message to the address you fill in. "Bcc" stands for "Blind carbon copy" which says: send a copy to another address...but in this case, don't indicate to the Fcc recipient that you also sent this copy.
