How to take back what you say? [also a short survey of news systems]
------------------------------
.The best time to retract a posting is BEFORE you send it. --ENM

Suppose you post an article and then later realize that you made a
horrible mistake.  Or suppose you made a post like an ad in ba.market.misc
which is no longer valid (sold or what not).
You really do not want anyone to see your article.
You want the article to be removed from any machines that it may
have reached. What you should do is cancel your article. This may not
remedy your mistake completely, but it will surely help.  In virtually
all cases sending another message saying "Please ignore my previous
article", will make things even worse (never seen in chronologically
important order).

MISPOSTED ARTICLE: If you have violated a newsgroup charter, please
consider this as a horrible mistake that should be cancelled without
any delay. Mispostings are a real nuisance to all readers, and they
have an annoying tendency to sprout long threads which clutter some
newsgroups completely.  By cancelling your non conforming article
_early_ you will contribute to a better usenet environment. Besides,
you may be able to avoid the flames and personal mailbox flooding which
may occur after such a mistake. Your cooperation will be appreciated!

WARNING: Cancels are not 100% effective--they do not traverse
news-to-mail gateways (or news-to-anything else gateways).  Remember
that there are propagation delays--a lot of sites receive news in daily
batches and your mistaken posting may stick around for a long time
before its cancel catches up with it--cancels ARE news articles--they
are EXPENSIVE just like news articles (remember that warning about
Are you sure you want to spend thousands of dollars of other people's
money?), and can get lost in transit just like other news articles.
(Also, some sites simply do not honor cancels!)


The rest of this message is intended to serve as a short tutorial which
should help you learn how how to cancel an article. 

Sometimes the newsreading program would refuse to cancel your article
for no apparent reason. This may be caused by a misconfiguration problem.
You should see your local news adminstrator should this or any other
problem occur.

General: Almost every news reader requires that you find the article
and start reading it before you may cancel it.  Once you have found
the article, please skip to the section regarding your news reader.
In general, the 'cancel this article' command should be bound to the 'c'
or 'C' keys.

NN:
.As you're reading your article, press the C key at the prompt.
.NN will then ask you to "Confirm cancel", just type the
.letter y.  It will then say "Cancelling article <article-id>
...." and then go on to the next selected article as if you
.had just finished reading that article and had hit the n key
.to go to the next article.

RN:
.At the article prompt, press the C key.  RN will then cancel
.the article for you and will re-display the article prompt.

TRN:
.At the article prompt, press the C key.  RN will then cancel
.the article for you and will re-display the article prompt.

.TRN is a nearly exact superset of rn, and all usual rn commands
.work just fine in trn..(Although the "next article" command
.means something different within threads!)


READNEWS:
.At the "More? [...]" prompt, type the lowercase letter c and
.then press the return key.  The article will then be cancelled
.and readnews will go on to show you the next article.

VNEWS (News reader on VAX/VMS):
.At the "more?" prompt, type the c key..VNEWS will then ask
.you to confirm by saying "cancel [n]?" at which point you press
.the y key.  VNEWS will then go on to display the next article.

VN:
.From within the article you would like to cancel, press
.'f' to followup.  At the top of the article, duplicate the
."References" line.  Chance "References" to "Control".  Then,
.put the word "cancel " before the message ID.  Finally,
.post your followup.

NOTES:
.Press the D key.  Notes will respond with "Delete?".  Type y.
.Notes sends out articles in batches.  If an article has
.already been transferred to the network the article will
.not be deleted.  Notes will not respond to a cancel message.
.It will only delete articles created locally.

ANU-NEWS:
.While reading an article, enter the "CANCEL" command at the
.NEWS> prompt.

VM:
.For VM, users using netnews (directly from disk, not via NNTP),
.must positioning the cursor on the article and type cancel.
.The NNR VM NNTP client doesn't have cancel possibilities.

TIN:
.After bringing up the message you would like to cancel, type
.a capital C.  In tin PL5, you will be asked to confirm this
.by hitting a lower-case c.  Other news readers I'm not sure
.about but it's probably a similar mechanism.
.In tin, it's actually "D" to delete article once you're viewing the
.article; then "d" to confirm.

XRN: Select your article so you're reading it in the article pane
of the xrn window.  Then, click on the "cancel" button which is at
the bottom of the xrn window.


TASS: A basic news reader: no cancel command.
Rich Skrenta   skrenta@blekko.commodore.com

GNUS:
.In Subject Mode: `C' Cancel the current article you posted
     (`gnus-Subject-cancel-article').
.[First select the offending article as current, then type `C'.]

I'm using WinVn/32-bit 0.99.7 which comes from a nasa.gov site. 
(ftp.ksu.nasa.gov as I recall) It seems to have a bug in cancelling.

It won't let you cancel if you have no organization name. That's why I have a 
fascetious organization name.

(I downloaded the source code after I found that it wouldn't let me 
cancel--it said only the poster could cancel but I was the poster--but I 
could cancel a WinVN article with News Express. I looked at what WinVN was 
checking and I found that it was checking the organization name. I tried 
setting an organization name and posting a test message and cancelling it and 
this worked.)
