DON'T include the entire contents of a previous posting in your reply.
DO cut mercilessly. Leave just enough to indicate what you're responding
to. NEVER include mail headers except maybe the "From:" line. If you
can't figure out how to delete lines in your mailer software, paraphrase
or type the quoted material in.
DON'T reply to a point in a posting without quoting or paraphrasing what
you're responding to and who said it. Reason: a dozen postings may
occur between the original message and your reply. At some sites your
reply may arrive before the original does.
DO quote (briefly) or paraphrase. If the original "Subject:" line was
"Big dogs" make sure yours says "Re: Big dogs". Some reply functions do
this automatically. By net convention, included (quoted) lines are
preceded by ">" (greater-than signs). Some mail editors and newsreaders
do this automatically. Others require you to do it manually or to set
the "indent character" to ">." Microsoft Exchange is the hardest to use
if you want to correspond on the Internet. Unless you're a Word expert,
you'll have to enter the ">" signs by hand and get rid of the mail
header and indentations. Some versions of Exchange client put the
cursor for your reply *before* the message you're replying to; how
useless! Move the cursor so that your readers will see the message
you're responding to first, then your response.
DON'T send a message saying, "Why doesn't anybody say anything about X?"
or "Who wants to talk about X?"
It's always a risk to start a new topic (often called a thread). The
group may have just finished a long, bitter war about that very subject.
But if you want to take the risk, SAY SOMETHING yourself about the
subject you're raising.
DON'T send lines longer than 70 characters. This is a kindness to folks
with terminal-based mail editors or newsreaders. Some mail and news
gateways truncate extra characters, turning your deathless prose into
gibberish.
Some mail and news editors only SEEM to insert line breaks for you but
actually don't, so that every paragraph is one immense line. Learn what
your mail and news editors do by mailing a message to yourself (or
posting it to alt.test) and reading the message in a couple of mail and
news readers. Unix mail or Mail (they're different) and nn and Netscape
Navigator's mail and news readers will usually let you read your message
in a plain, vanilla form, the way others will see it.
DON'T SEND A MESSAGE IN ALL CAPS. CAPITALIZED MESSAGES ARE HARDER TO
READ THAN LOWER CASE OR MIXED CASE.
DO use normal capitalization. Separate your paragraphs with blank
lines. Make your message inviting to your potential readers.
DON'T betray confidences. It's all too easy to quote a personal message
by mistake in a message to the entire group.
DO read the "To:" and "Cc:" lines in your message before you send it.
Are you SURE you want the message to go there?
DON'T make statements which can be interpreted as official positions of
your organization or offers to do business. Saying "Boy, I'd sure like
to have one of those new supercomputers" could result in a truck at your
loading dock and a bill in the mail even larger than your student loan.
DO treat every post as though you were sending a copy to your boss, your
minister, and your worst enemy. I customarily end every message I send
from work with "Speaking for myself, not my company."
DON'T rely on the ability of your readers to tell the difference between
serious statements and satire or sarcasm. It's hard to write funny.
It's even harder to write satire.
DO remember that no one can hear your tone of voice. Use emoticons (or
smileys) like :-) or ;^) -- tilt your head counterclockwise to see the
smile. You can also use caps for emphasis or use net conventions for
italics and underlines as in: You said the guitar solo on "Comfortably
Numb" from Pink Floyd's _The Wall_ was *lame*? Are you OUT OF YOUR
MIND???!!!
Some mail editors (Exchange again) let you insert all kinds of special
characters and put your text in boldface, italics or different fonts.
Don't give in to the temptation to use those features unless you're
certain that everyone whom you intend to read your message has the same
editor.
DON'T put a huge signature at the bottom of your messages.
DO exercise some restraint. Remember that a large number of mail and
news readers out there are set up to use proportional fonts, and your
lovely ASCII art will look nothing like you intended it to on those
readers. Remember also that there's a Usenet newsgroup out there
whose sole function is to make fun of people's signatures. Try not to
appear there.
DON'T send a message that says nothing but "Me, too." This is most
annoying when combined with (1) or (2) above. Ditto for "I don't know."
DO recall that you aren't obligated to reply to every single thing you
read. Remember the immortal words of Martin Farquhar Tupper
(1810-1889): "Well-timed silence hath more eloquence than speech."
