+Of course, there is no Underground---or Untergrund, as those German
+new-age kids like to call the movement whose orders they
+have sworn to follow.  The age we all remember---the cliff-green
+turbocharged convertibles, cigarettes hanging loose in the corners of
+our mouths, and those trigger-happy fingers always ready for the quick
+hack---is long gone.
+
+In retrospect, it all seems like a candy-colored dream, and it may
+very well be---after all, there was never any proof that the
+Untergrund ever existed, and even if there was, we can be sure the
+obedient followers of the shadowy movement leaders have long burned
+the papers, subjected the hard drives and diskettes to interminable
+sessions of the junkyard magnet, and eradicated all shreds of
+memory from the brains of those who might have talked through long
+sessions of Tcl hacking to the sounds of Celine Dion records.
+
+Yet there are those who still covet membership in that secret
+cult---to gain access to its powerful lore, to usurp invidious and
+powerful superiors, or simply to impress their girlfriends.  For those
+lost souls of the modern age, I have a few words of advice:
+
+It's not a question of ``membership''---silly merchandise and
+ridiculous certificates.  If you are truly meant to be part of the
+Untergrund, you will know.  \emph{The Untergrund will find you.}
+
+Alas, probably not.
