And remember to do the world a favor and un-do that change when the immediate
problem is past. :)

Another good way to avoid annoyed replies is to not have disclaimers longer than
the actual posting.  My favorite:

"... if you are not an intended recipient, you must not copy, distribute or
take any action in reliance on it."

Do you have any legal citations to justify a "must" as opposed to a "pretty please
with sugar on it"?

"If this message is being transmitted over the Internet, be aware that it may
be intercepted by third parties."

http://www.openpgp.org/resources/downloads.shtml and pick something.  It's more
effective than a disclaimer.
