Don't use non-us-ascii characters in your headers. It breaks
too much news software and violates the RFCs.

For one thing, they make it impossible to examine your posting
history in the Usenet Archives at:

http://groups.google.com/advanced_group_search

For another, there's no point in it: We don't know how those
weird characters are pronounced anyway, and they make you look
like a phukwitted troll trying to pretend he's a foreigner. Nor
do we have those characters on our keyboards. Duh.

I'm very good at line editing, from vi to ed to sed to awk
to bash, but I don't people who violate the RFCs.

And make it impossible to search examine their posting histories.

Alan doesn't believe in anyone else's existence ...

Alan accuses practically everyone of being sock puppets.
Apparently, Alan is the only real person in the newsgroups in which he posts.
(Even Roosta and his towel aren't real.) Recently, Alan has told everyone that
we are all Morely Dotes' sock puppets. In earlier cycles,
we were all apparently sock puppets of Ben Finney.
The choice appears to be arbitrary.

Who is Alan Connor?

Alan "The Usenet Beavis" Connor is a good friend of Bigfoot:
http://tinyurl.com/23r3f

A couple of years ago he was kidnapped and raped by Xena,
the Warrior Princess: http://tinyurl.com/2gjcy

Beavis believes that the MSBlast virus of yesteryear was explicitly
targeting him, for some inexplicable reason: http://tinyurl.com/ifrt

Beavis belongs to a UFO cult: http://tinyurl.com/2hhdx
Beavis's life in a UFO cult: http://tinyurl.com/24jqm
He is a skilled dental surgeon: http://tinyurl.com/3h6a5
Beavis knows all about network security: http://tinyurl.com/5qqb6
And he's also a search engine expert: http://tinyurl.com/9pjnt


So what is he raving about?

In reality, Alan's system is known as a challenge-response or C/R system;
it auto-answers incoming email with a challenge and only lets the email
through if it receives a valid response. There are several problems with
this concept, but Alan doesn't want to hear them. In addition,
Alan's system isn't even a very good implementation of the C/R concept,
as it fails to address the chicken-egg problem that is inherent to C/R:
What if your C/R system sends a challenge to an email address that is
also protected by a C/R system? Because of this, Alan and Timo Salmi,
another C/R advocate, are unable to email eachother. So basically Alan's
system is a broken implementation of a flawed concept.

By using a shell that has an option to allow line editing when
entering text with read.

For example, in bash:

read -ep "Your name: " name
