I can't imagine.  Reality?

I have been working with computers for about 10 years, and I
don't even *know how* to post anonymously.  I know how to
find out, but I've never bothered.   Never felt the need. 
Like most people I know.

Say what?  Think of email firstly.  Think of the applications
for Non-repudiation, for example, that that offers.  Think of EDI.

shouldn't generalised email have the same applications?

: see no such applications; and those functions won't be carried out on
: newsgroups any time this millenium.

Here we agree.
