Not to be unkind but, please:
a) get rid of all this PGP signature nonsense
b) post the question in the body rather than just the subject line

As others have said, with a message this short please ditch the pgp crap. I
don't care who is asking, if I know I will generally answer.
In this case the answer is the wall command.

Dear Nerd,
Your subject line isn't covered by your cryptographic signature, so I
cannot trust that it wasn't forged.
Therefore, I fear cannot answer it.

Wrong. That should be: ``With a message which has absolutely no
security implications, regardless of its length, ditch the PGP crap.''

I am sorry!
I learn to use gpg just because I seem
some body in mailing list use it.
Sorry again, I will remove the gpg signature
from now!

Let me be the first to encurage you to use gpg.
I use gpg in all my messages in order to proove that I was the one writing
the message and not someone pretending to be me.
If people have problems with gpg signatures, then let them ignore it.
You are not the only one that use gpg. :-)=

You prove no such thing by doing so. All you do is prove a signing
operation was performed on two or more messages using the same key.
That doesn't prove anything about who did the signing, or even that it
was a single individual. The key could be shared by a multitude.
Anyone can install GPG and create throwaway keys, the same way that
anyone can create a yahoo or hotmail e-mail account. It means
absolutely nothing. You could repudiate everything which was posted
with that GPG key, and claim that it was just someone pretending to be
you who created that key.
Besides, in a forum like Usenet, what you typically want to prove is
that it was /not/ you who wrote something, not that it /was/. The
/lack/ of a signature does not prove that it was /not/ you. After all,
if you were going to post something that you wanted to repudiate, of
course you would not sign it.
Digital signatures are for proving your identity when the authenticity
matters. For instance, if your banker were to receive instructions to
transfer a large sum out of your bank account, he might want proof that
it's really you making the request.
So, in short, all you are doing is showing the world that you're a
complete idiot when it comes to cryptography.
> If people have problems with gpg signatures, then let them ignore it.
Note that the signatures violate Usenet netiquette.

I second what Ed said.

might be what you want.
Or you could do something like this:
# echo -e "\n\n\nHello World\n\n\n" > /dev/ttyp1 && echo -e "\n\n\nHello World\n\n\n" > /dev/ttyp2...
But if they are running X, it would probably be better to create a
new, small xterm "popup" with the message in it, something like:
aterm -title "oo" -rv -fn "-*-courier-medium-r-normal-*-*-120-*-*-*-*-iso8859-1" -geometry 30X10+10+20 -sl 300 -e `echo\n\n\n...'
Not sure how to get that to the current window of each user.
There's probably an X utility that does that, which could likewise
be called in a script.

So you believe that every time you post a message it is profound?
Excuse me, but why would we care?
Oh - You like gpg. I better find out if it's really you who said
this. Because if a complete stranger said it, my entire world would
turn upside down. Oh no. I'm falling to the ceiling. Aaaaaagh..
