With respect to the invitation to join a pyramid posted by J Smith (undoubtedly a pseudonym) and the warning from Brian Lawson that replying to Mr Smith's spam would put you on their mailing list.
My Fire Wall, "Zone Alarm Suite" detected that opening and reading Mr Smith's message, resulted in the deposition of two "cookies" on my computer. These cookies are called "About" and "Serving-Sys". They track my key strokes and report back to the originator my computer activities. Mr Smith will know all about you without you having to reply to his message.
Fortunately my Fire Wall detected and deleted these cookies. Most people will not be so lucky.
Would the administrator of this list please delete Mr Smith's spam. Please!
