CNET GLOSSARY: Terms for the techie
A computer that strips away identifying information, such as an e-mail address, before passing a message on to another e-mail address or a newsgroup. When you send messages using a remailer, the From: field of your message becomes a made-up address, such as firstname.lastname@example.org.
There are two kinds of services in this category. The first is truly anonymous: no one anywhere knows your identity. With the second, called pseudo-anonymous or sometimes pseudonymous, the owner of the service knows your identity and can be forced in a court of law to reveal it. Most truly anonymous services are free (it's difficult to bill an unknown, unnamed client), but they often require some skill and effort to use. Many pseudo-anonymous services charge a fee but are more user-friendly.
