Email convention
****************

When you exchange messages with other people, you should obey minimum
manner. It gives a bad impression to the people if you violate the
manner since such messages are hard to read. We always should try to
write concise yet comprehensive explanations and make an effort to
make receivers well-understood.

We should take good care of the following items.

Fill To: and Cc: fields precisely
     To: is for target receivers and Cc: is for those who are received
     for their information. If his address is not on To:, he might
     skip to read the message. We should take care not to deliver to
     wrong people by mistaking the addresses.

Write a short and clear summary of body in Subject:
     There are people who decide to read contents from their
     Subject:. So, they might skip messages with improper Subject:. We
     should not write a long subject since it is hard to read.

Carriage return means end of line and null line expresses end of paragraph. One line should be limited to 70 characters or so.
     It is very hard to read if you write a message on every other
     line or in a long line without folding. Especially long lines are
     trouble to cite. Some people write a message with indent but it
     is meaningless. Text is displayed differently on each machines,
     so even if the layout is excellent on your machine, it might not
     be so on other machines.

Cite only necessary sentences
     You should not bother to remove unnecessary sentences. With Mew,
     citation must be a piece of cake.

Make your signature simple
     A long signature is just self-satisfaction.

Never send prank messages
     I don't want to warn this kind of stuff. Nonetheless, someone
     sends Happy or Unhappy messages to others. You should understand
     that people doubt your character.
