Try to stay on topic -- but realize that topics will wander, just as a regular conversation might.
If a topic wanders, be patient, tune out or change the subject.
Keep your messages short -- succinct is good. Long and rambling is not.
Spelling and grammar do matter. The Internet is a written medium,
and poorly written or sloppy messages make it hard for other users to take the content seriously.
Don't guess -- if you don't know the answer to a question, don't guess. Look it up, or let someone else answer it.
There are few things more frustrating than asking a question and getting four different answers, only one of which can be right
-- and not knowing which one is.
Edit included messages in replies to minimize the amount of text. The more you surround your words with included text in a message,
the less likely people will find and read them.
Make sure your subject line is accurate. The number one complaint we get these days are people who are subscribed to the digest,
and reply to a message without changing the subject line -- leaving the generic digest subject on the message.
Please don't do this -- take a couple of seconds to change the subject.
