+@node To From Newsgroups
+@subsection To From Newsgroups
+@cindex To
+@cindex Newsgroups
+
+In some groups (particularly in archive groups), the @code{From} header
+isn't very interesting, since all the articles there are written by
+you. To display the information in the @code{To} or @code{Newsgroups}
+headers instead, you need to decide three things: What information to
+gather; where to display it; and when to display it.
+
+@enumerate
+@item
+@vindex gnus-extra-headers
+The reading of extra header information is controlled by the
+@code{gnus-extra-headers}. This is a list of header symbols. For
+instance:
+
+@lisp
+(setq gnus-extra-headers
+ '(To Newsgroups X-Newsreader))
+@end lisp
+
+This will result in Gnus trying to obtain these three headers, and
+storing it in header structures for later easy retrieval.
+
+@item
+@findex gnus-extra-header
+The value of these extra headers can be accessed via the
+@code{gnus-extra-header} function. Here's a format line spec that will
+access the @code{X-Newsreader} header:
+
+@example
+"%~(form (gnus-extra-header 'X-Newsreader))@@"
+@end example
+
+@item
+@vindex gnus-ignored-from-addresses
+The @code{gnus-ignored-from-addresses} variable says when the @samp{%f}
+summary line spec returns the @code{To}, @code{Newsreader} or
+@code{From} header. If this regexp matches the contents of the
+@code{From} header, the value of the @code{To} or @code{Newsreader}
+headers are used instead.
+
+@end enumerate
+
+@vindex nnmail-extra-headers
+A related variable is @code{nnmail-extra-headers}, which controls when
+to include extra headers when generating overview (@sc{nov}) files.
+
+In summary, you'd typically do something like the following:
+
+@lisp
+(setq gnus-extra-headers
+ '(To Newsgroups))
+(setq nnmail-extra-headers gnus-extra-headers)
+(setq gnus-summary-line-format
+ "%U%R%z%I%(%[%4L: %-20,20f%]%) %s\n")
+(setq gnus-ignored-from-addresses
+ "Your Name Here")
+@end lisp
+
+Now, this is mostly useful for mail groups, where you have control over
+the @sc{nov} files that are created. However, if you can persuade your
+nntp admin to add:
+
+@example
+Newsgroups:full
+@end example
+
+to the end of her @file{overview.fmt} file, then you can use that just
+as you would the extra headers from the mail groups.

+score} is not necessarily related to normal scores.)
@end enumerate
-A predicate consists of predicates with logical operators sprinkled in
-between.
+A predicate in its simplest form can be a single predicate such as
+@code{true} or @code{false}. These two will download every available
+article or nothing respectively. In the case of these two special
+predicates an additional score rule is superfluous.
+
+Predicates of @code{high} or @code{low} download articles in respect of
+their scores in relationship to @code{gnus-agent-high-score} and
+@code{gnus-agent-low-score} as descibed below.
+
+To gain even finer control of what is to be regarded eligible for
+download a predicate can consist of a number of predicates with logical
+operators sprinkled in between.
Perhaps some examples are in order.
@code{gnus-headers} and @code{gnus-score} dynamic variables are bound to
useful values.
+For example, you could decide that you don't want to download articles
+that were posted more than a certain number of days ago (e.g. posted
+more than @code{gnus-agent-expire-days} ago) you might write a function
+something along the lines of the following:
+
+@lisp
+(defun my-article-old-p ()
+ "Say whether an article is old."
+ (< (time-to-day (date-to-time (mail-header-date gnus-headers)))
+ (- (time-to-day (current-time)) gnus-agent-expire-days)))
+@end lisp
+
+with the predicate then defined as:
+
+@lisp
+(not my-article-old-p)
+@end lisp
+
+or you could append your predicate to the predefined
+@code{gnus-category-predicate-alist} in your @file{~/.gnus.el} or
+wherever. (Note: this would have to be at a point *after*
+@code{gnus-agent} has been loaded via @code{(gnus-agentize)})
+
+@lisp
+(defvar gnus-category-predicate-alist
+ (append gnus-category-predicate-alist
+ '((old . my-article-old-p))))
+@end lisp
+
+and simply specify your predicate as:
+
+@lisp
+(not old)
+@end lisp
+
+If/when using something like the above, be aware that there are many
+misconfigured systems/mailers out there and so an article's date is not
+always a reliable indication of when it was posted. Hell, some people
+just don't give a damm.
+
+
+The above predicates apply to *all* the groups which belong to the
+category. However, if you wish to have a specific predicate for an
+individual group within a category, or you're just too lazy to set up a
+new category, you can enter a group's individual predicate in it's group
+parameters like so:
+
+@lisp
+(agent-predicate . short)
+@end lisp
+
+This is the group parameter equivalent of the agent category
+default. Note that when specifying a single word predicate like this,
+the @code{agent-predicate} specification must be in dotted pair
+notation.
+
+The equivalent of the longer example from above would be:
+
+@lisp
+(agent-predicate or high (and (not low) (not long)))
+@end lisp
+
+The outer parenthesis required in the category specification are not
+entered here as, not being in dotted pair notation, the value of the
+predicate is assumed to be a list.
+
+
Now, the syntax of the download score is the same as the syntax of
normal score files, except that all elements that require actually
seeing the article itself are verboten. This means that only the
-following headers can be scored on: @code{From}, @code{Subject},

+@item (nnchoke-request-set-mark GROUP ACTION &optional SERVER)
+
+Set/remove/add marks on articles. Normally Gnus handles the article
+marks (such as read, ticked, expired etc) internally, and store them in
+@code{~/.newsrc.eld}. Some backends (such as IMAP) however carry all
+information about the articles on the server, so Gnus need to propagate
+the mark information to the server.
+
+ACTION is a list of mark setting requests, having this format:
+
+@example
+(RANGE ACTION MARK)
+@end example
+
+Range is a range of articles you wish to update marks on. Action is
+@code{set}, @code{add} or @code{del}, respectively used for removing all
+existing marks and setting them as specified, adding (preserving the
+marks not mentioned) mark and removing (preserving the marks not
+mentioned) marks. Mark is a list of marks; where each mark is a
+symbol. Currently used marks are @code{read}, @code{tick}, @code{reply},
+@code{expire}, @code{killed}, @code{dormant}, @code{save},
+@code{download} and @code{unsend}, but your backend should, if possible,
+not limit itself to theese.
+
+Given contradictory actions, the last action in the list should be the
+effective one. That is, if your action contains a request to add the
+@code{tick} mark on article 1 and, later in the list, a request to
+remove the mark on the same article, the mark should in fact be removed.
+
+An example action list:
+
