Some people---mostly immature teenagers and young adults---believe that "information
wants to be free." It doesn't work that way, as all PBase subscribers well know.

In that light, information that is valued must be protected. This access controller
(in some circles called a "block signal array") works with the password processor
( http://www.pbase.com/listorama/image/55931633 ), to control who gets access to
galleries and images. In this photo, requests for access come from the left. When a
surfer approaches a gallery or an image, system visual indicators called "lights" are
activated to display the appropriate access status. The default is a "green light,"
meaning "the requestor may proceed to the target." This allows a surfer to
cruise in without being blocked. Having to stop here could cause the
surfer to rant and rail, if you get my drift.

But how does this work? For you geeks and technofreaks, here's a synopsis. The
controller detects and captures the attempted intrusion and the identity of the
desired target. It then sends this data to the password processor, which
determines if the desired target has been flagged with a "red light." (This
flagging takes place based on various conditions and cannot be predicted in
advance.) The processor replies to the controller with either a "red" or "green"
signal. If it's a "green" signal, the controller is unchanged. If it's a "red"
signal, the controller changes color, blocks access, and informs the surfer to "get lost."
