How do I anonymous post to usenet?

"Anonymous Coward" is a term applied within some online communities to describe users who post without a screen name; it is a dummy name attributed to anonymous posts used by some weblogs that allow posting by people without registering for accounts. The practice originated on Slashdot, where the mildly derogatory term is meant to chide anonymous contributors into logging in. Some weblog engines such as Scoop use the term "Anonymous Hero" instead, perhaps to avoid the name's confrontational nature. Others use stronger varieties, like Plastic.com's "Anonymous Idiot". 4chan is an imageboard where its /b/ board forces anonymous posting.
