Using e-mail is rather straightforward. You can type anything you want as the subject and body, although the length of the subject is limited. You usually want to keep the subject to just a few words describing the content of the body of the e-mail message. You may also see options for attachments and forwards. You can add files to your e-mail by using the attachment option.
CC stands for carbon copy.
BCC stands for blind carbon copy. BCC works just like a carbon copy, except the e-mail addresses you type in BCC do not show up to the other recipients. There are two things about file attachments you need to be careful of. The first thing is that you need to limit the size of files you are sending. Get permission before sending large files to someone.
