-  Once something is posted onto the network, it is *probably* in the
-  public domain unless you own the appropriate rights (most notably,
-  if you wrote the thing yourself) and you post it with a valid
-  copyright notice; a court would have to decide the specifics and
-  there are arguments for both sides of the issue. Now that the US has
-  ratified the Berne convention, the issue is even murkier (if you are
-  a poster in the US).  For all practical purposes, though, assume
-  that you effectively give up the copyright if you don't put in a
-  notice.  Of course, the *information* becomes public, so you mustn't
-  post trade secrets that way.

-  When posting material to the network, keep in mind that material
-  that is UNIX-related may be restricted by the license you or your
-  company signed with AT&T and be careful not to violate it.  You
-  should also be aware that posting movie reviews, song lyrics, or
-  anything else published under a copyright could cause you, your
-  company, or members of the net community to be held liable for
-  damages, so we highly recommend caution in using this material.
+  Before posting to Usenet or reproducing something that has been posted to
+  Usenet, make sure you read the accompanying posting "Copyright Myths FAQ:
+  10 big myths about copyright explained".  At the very least, note that by
+  posting to Usenet, you are requesting that a copy of your document be
+  automatically distributed to computers all over the world and stored on
+  various disks for a long time (forever on some archive media).
+
+  Further, some people will quote parts of your article without permission
+  or forward it to other people or use it in other ways that you might not
+  know about.  If this bothers you, put an explicit copyright notice on
+  your posting.  On the flip side, even if you are sure of the legality of
+  reproducing something from or on Usenet, it would be courteous to ask for
+  permission before doing so.
