Choose Options from the Menu bar at the top of the Netscape window, and locate Mail preferences (different versions of Netscape handle this variously). You will need to enter a Name (it doesn't really care what you put, as long as there's something in the field) and your E-mail address (it does care about that, but you can leave the rest of the fields blank).
You may also need to identify the Outgoing Mail (SMTP) server: enter wlu.edu in the space provided under Servers. There's no need to enter anything for the Incoming Mail (POP) Server.
Once these bits are filled in you can choose "Mail Document" from the Netscape File menu. You'll have to fill in the destination (usually yourself) and click the QUOTE button to make the text appear in the body of the message. Then click the Send button.
Netscape's Mail has other capabilities that we won't go into here. You might want to remove the information from the Mail preferences when you're finished, since it's probably a public machine that you're using.
