Eric Melton did several articles for GDW's _Challenge_, including "The Sweet Trade in Space: Piracy" in #41, "Catch and Carry Team" in #45, "SAMN" in #56, and "Catch as Catch Can" in #62. The focus of all of these articles dealt with some aspects of 24th Century piracy. They were all very interesting, and generally well-done (although it seems to me that he left the effects of Navigational RaDAR out of his "Piracy" article).
Unfortunately, Erick hasn't granted me permission to host his articles, so I can't, for Copyright reasons. If you can find the appropriate issues of _Challenge_ Magazine, you can read them, there. Here is a list of possible sources.
