Subject: No German From You Unless It's Your Native Language, I'm English.
From: German_Sender@
Sender: German_Sender@

			I append http://www.berklix.com/~jhs/std/no_german.txt

Thanks for your mail, 
I'm English, Please do Not write in German if that's not your first
language.  I can read German, but much prefer English. Unless you
are actually a native speaker of German, do not mail me in German !

I used to get too many Americans with German ancestry assuming I'm
German, & writing me in half baked German ! My German grammar is
also half baked, & real German grammar bad enough, so it would be
foolish to lead each other astray, puzzling about & maybe worse,
even learning each other's faulty grammar, so do not mail me in
German unless you Are German (or Austrian etc)

- Some people write to me in German because they see a .de in a
  domain, or mention of Munich/ Muenchen etc, even though all my
  prior mail discussion has been in English on international mail
  lists.  Wrong deduction ! I'm not German !  I am English.
- Perhaps people are being friendly or helpful or practising their
  German on me, learnt at school, or with USA German ancestry etc, but ...
- Though my German is good enough for me to read real German, it is easily
  confused, & I really don't wwant to wade through unsolicited-
  switched- to- quasi- maybe- German, when I must both try to
  understand the meaning, and simultaneously guess if (A) this is
  _proper_ German where I should learn the grammar, or (B) this is
  quasi junk German from a non native German speaker, with perhaps
  as many but different mistakes as I make, where learning the
  sender's grammar could be deleterious.

Exceptions
  Unless there's someone on CC: who can't read (not can't write) English.
  Unless you're quoting or preparing a German text or publication.

PS
If you first language is French you could also write short notes in 
simple French, but Not unless you are a native French speaker.
