Someone, who's shall remain nameless, sent this to FoRK.  These have been 
showing up with greater frequency.

One of those received yesterday broke my mail program (Eudora 5.1), and all 
the following messages (I get the digest) were continuations of the noise 
(probably because the "------=_NextPart_00 ..." terminator was missing).

Peace,
