When I first go my mac II i went throught many of the old archves of
this and another group.  I no longer keep them around (too big), but several
things stood out.  One was the the message about screens hurting eyes.
Thought I no longer have the old messages, IF MEMORY SERVES ME CORRECTLY
the enclosed copy is yet another identical copy of the same message.

Why?  Is the poster a lawyer ?  I think an explanation is in
order.
