*is* knowledgeable about what's possible]

....but the others...well...

The world experts on this newsgroup are just that. We have experts
on ACF who can analyse headers and tell everything about the poster,
even what you had for lunch. Ron May's one example. Franklin (rotfl)
is another, iNcReduLoUs (rotfl x 10) is another. They do it all the
time to prove to their satisfaction who the spoofers/sockpuppets are

Here's a few of your headers which they would swear until death,
reveal what s/w you use to post, what server you posted through
etc etc etc.

That it can all be easily manipulated for security reasons or to
imply that a post was made by another person goes completely
over their heads.
