The people who register on messages boards, post one time, then disappear, never to be seen again.

The post that they post is usually a nonsensical one that only a select few might understand, but normally leaving much to the imagination.

A One Post Wonder may contain anything from smileys, the word "Hi", to the more common spam.

Member 1: What was that about?

Member 2: I've got no idea.
