+Gnus uses this estimation because the NNTP protocol provides efficient

@item admin-address
+@cindex admin-address
When unsubscribing from a mailing list you should never send the

messages to the administrative address. This parameter allows you to
put the admin address somewhere convenient.
@item display
+@cindex display
Elements that look like @code{(display . MODE)} say which articles to
display on entering the group. Valid values are:
@item default
Display the default visible articles, which normally includes unread and
ticked articles.
+
+@item an array
+Display articles that satisfy a predicate.
+
+Here are some examples:
+
+@table @code
+@item [read]
+Display only read articles.
+
+@item [not expire]
+Display everything except expirable articles.
+
+@item [and (not reply) (not expire)]

@item posting-style
+@cindex posting-style
You can store additional posting style information for this group only
here (@pxref{Posting Styles}). The format is that of an entry in the
@code{gnus-posting-styles} alist, except that there's no regexp matching
(signature "Funky Signature"))

@item banner
+@cindex banner
An item like @code{(banner . "regex")} causes any part of an article
that matches the regular expression "regex" to be stripped. Instead of
"regex", you can also use the symbol @code{signature} which strips the
silly Lisp errors.) You might also be interested in reading about topic
parameters (@pxref{Topic Parameters}).
+Group parameters can be set via the @code{gnus-parameters} variable too.

+@cindex delayed sending
+@cindex send delayed
+
+Sometimes, you might wish to delay the sending of a message. For
+example, you might wish to arrange for a message to turn up just in time
+to remind your about the birthday of your Significant Other. For this,
+there is the @code{gnus-delay} package. Setup is simple:
+
+@lisp
+(gnus-delay-initialize)
+@end lisp
+
+@findex gnus-delay-article
+Normally, to send a message you use the @kbd{C-c C-c} command from
+Message mode. To delay a message, use @kbd{C-c C-j}
+(@code{gnus-delay-article}) instead. This will ask you for how long the
+message should be delayed. Possible answers are:
+
+@itemize
+@item
+A time span. Consists of an integer and a letter. For example,
+@code{42d} means to delay for 42 days. Available letters are @code{m}
+(minutes), @code{h} (hours), @code{d} (days), @code{w} (weeks), @code{M}
+(months) and @code{Y} (years).
+
+@item
+A specific date. Looks like @code{YYYYY-MM-DD}. The message will be
+delayed until that day, at a specific time (eight o'clock by default).
+See also @code{gnus-delay-default-hour}.
+
+@item
+A specific time of day. Given in @code{hh:mm} format, 24h, no am/pm
+stuff. The deadline will be at that time today, except if that time has
+already passed, then it's at the given time tomorrow. So if it's ten
+o'clock in the morning and you specify @code{11:15}, then the deadline
+is one hour and fifteen minutes hence. But if you specify @code{9:20},
+that means a time tomorrow.
+@end itemize
+
+The action of the @code{gnus-delay-article} command is influenced by a
+couple of variables:
+
+@table @code
+@item gnus-delay-default-hour
+@vindex gnus-delay-default-hour
+When you specify a specific date, the message will be due on that hour
+on the given date. Possible values are integers 0 through 23.
+
+@item gnus-delay-default-delay
+@vindex gnus-delay-default-delay
+This is a string and gives the default delay. It can be of any of the
+formats described above.
+
+@item gnus-delay-group
+@vindex gnus-delay-group
+Delayed articles will be kept in this group on the drafts server until
+they are due. You probably don't need to change this. The default
+value is @code{"delayed"}.
+
+@item gnus-delay-header
+@vindex gnus-delay-header
+The deadline for each article will be stored in a header. This variable
+is a string and gives the header name. You probably don't need to
+change this. The default value is @code{"X-Gnus-Delayed"}.
+@end table
+
+The way delaying works is like this: when you use the
+@code{gnus-delay-article} command, you give a certain delay. Gnus
+calculates the deadline of the message and stores it in the
+@code{X-Gnus-Delayed} header and puts the message in the
+@code{nndraft:delayed} group.
+
+And whenever you get new news, Gnus looks through the group for articles
+which are due and sends them. It uses the @code{gnus-delay-send-drafts}
+function for this. By default, this function is added to the hook
+@code{gnus-get-new-news-hook}. But of course, you can change this.
+Maybe you want to use the demon to send drafts? Just tell the demon to
+execute the @code{gnus-delay-send-drafts} function.
+
+@table @code
+@item gnus-delay-initialize
+@findex gnus-delay-initialize
+By default, this function installs the @kbd{C-c C-j} key binding in
+Message mode and @code{gnus-delay-send-drafts} in
+@code{gnus-get-new-news-hook}. But it accepts two optional arguments,
+@code{no-keymap} and @code{no-check}. If @code{no-keymap} is non-nil,
+the @kbd{C-c C-j} binding is not intalled. If @code{no-check} is
+non-nil, @code{gnus-get-new-news-hook} is not changed.
+
+For example, @code{(gnus-delay-initialize nil t)} means to change the
+keymap but not to change @code{gnus-get-new-news-hook}. Presumably, you
+want to use the demon for sending due delayed articles. Just don't
+forget to set that up :-)

+@cindex archiving mail
+@cindex backup of mail
+
+Some of the backends, notably nnml and nnfolder, now actually store
+the article marks with each group. For these servers, archiving and
+restoring a group while preserving marks is fairly simple.
+
+(Preserving the group level and group parameters as well still
+requires ritual dancing and sacrifices to the @code{.newsrc.eld} deity
+though.)
+
+To archive an entire @code{nnml} or @code{nnfolder} server, take a
+recursive copy of the server directory. There is no need to shut down
+Gnus, so archiving may be invoked by @code{cron} or similar. You
+restore the data by restoring the directory tree, and adding a server
+definition pointing to that directory in Gnus. The @ref{Article
+Backlog}, @ref{Asynchronous Fetching} and other things might interfer
+with overwriting data, so you may want to shut down Gnus before you
+restore the data.
+
+It is also possible to archive individual @code{nnml} or
+@code{nnfolder} groups, while preserving marks. For @code{nnml}, you
+copy all files in the group's directory. For @code{nnfolder} you need
+to copy both the base folder file itself (@code{FOO}, say), and the
+marks file (@code{FOO.mrk} in this example). Restoring the group is
+done with @kbd{G m} from the Group buffer. The last step makes Gnus

+@node Scoring On Other Headers
+@section Scoring On Other Headers
+@cindex scoring on other headers
+
+Gnus is quite fast when scoring the ``traditional''
+headers---@samp{From}, @samp{Subject} and so on. However, scoring
+other headers requires writing a @code{head} scoring rule, which means
+that Gnus has to request every single article from the backend to find
+matches. This takes a long time in big groups.
+
+Now, there's not much you can do about this for news groups, but for
+mail groups, you have greater control. In the @pxref{To From
+Newsgroups} section of the manual, it's explained in greater detail what
+this mechanism does, but here's a cookbook example for @code{nnml} on
+how to allow scoring on the @samp{To} and @samp{Cc} headers.
+
+Put the following in your @file{.gnus.el} file.
+
+@lisp
+(setq gnus-extra-headers '(To Cc Newsgroups Keywords)
+ nnmail-extra-headers gnus-extra-headers)
+@end lisp
+
+Restart Gnus and rebuild your @code{nnml} overview files with the
+@kbd{M-x nnml-generate-nov-databases} command. This will take a long
+time if you have much mail.
+
+Now you can score on @samp{To} and @samp{Cc} as ``extra headers'' like
+so: @kbd{I e s p To RET <your name> RET}.
+
+See? Simple.

Currently Gnus uses the following formatting variables:
Note that the @samp{%(} specs (and friends) do not make any sense on the
mode-line variables.
+@node Positioning Point
+@subsection Positioning Point
+
+Gnus usually moves point to a pre-defined place on each line in most
+buffers. By default, point move to the first colon character on the
+line. You can customize this behaviour in three different ways.
+
+You can move the colon character to somewhere else on the line.
+
+@findex gnus-goto-colon
+You can redefine the function that moves the point to the colon. The
+function is called @code{gnus-goto-colon}.
+
+But perhaps the most convenient way to deal with this, if you don't want
+to have a colon in your line, is to use the @samp{%C} specifier. If you
+put a @samp{%C} somewhere in your format line definition, Gnus will
+place point there.

+@node Tabulation
+@subsection Tabulation
+
+You can usually line up your displays by padding and cutting your
+strings. However, when combining various strings of different size, it
+can often be more convenient to just output the strings, and then worry
+about lining up the following text afterwards.
+
+To do that, Gnus supplies tabulator specs--@samp{%=}. There are two
+different types---@dfn{hard tabulators} and @dfn{soft tabulators}.
+
+@samp{%50=} will insert space characters to pad the line up to column
+50. If the text is already past column 50, nothing will be inserted.
+This is the soft tabulator.
+
+@samp{%-50=} will insert space characters to pad the line up to column
+50. If the text is already past column 50, the excess text past column
+50 will be removed. This is the hard tabulator.
+
+
+@node Wide Characters
+@subsection Wide Characters
+
+Proportional fonts in most countries have characters of the same width.
+Some countries, however, use Latin characters mixed with wider
+characters---most notable East Asian countries.
+
+The problem is that when formatting, Gnus assumes that if a string is 10
+characters wide, it'll be 10 Latin characters wide on the screen. In
+these coutries, that's not true.
+
+@vindex gnus-use-correct-string-widths
+To help fix this, you can set @code{gnus-use-correct-string-widths} to
+@code{t}. This makes buffer generation slower, but the results will be
+prettieer. The default value is @code{nil}.

-- they have a group, and they deliver info on that group and nothing
more.
+Gnus identifies each message by way of group name and article number. A
+few remarks about these article numbers might be useful. First of all,
+the numbers are positive integers. Secondly, it is normally not
+possible for later articles to `re-use' older article numbers without
+confusing Gnus. That is, if a group has ever contained a message
+numbered 42, then no other message may get that number, or Gnus will get
+mightily confused.@footnote{See the function
+@code{nnchoke-request-update-info}, @ref{Optional Backend Functions}.}
+Third, article numbers must be assigned in order of arrival in the
+group; this is not necessarily the same as the date of the message.
+
+The previous paragraph already mentions all the `hard' restrictions that
+article numbers must fulfill. But it seems that it might be useful to
+assign @emph{consecutive} article numbers, for Gnus gets quite confused
+if there are holes in the article numbering sequence. However, due to
+the `no-reuse' restriction, holes cannot be avoided altogether. It's
+also useful for the article numbers to start at 1 to avoid running out
+of numbers as long as possible.
