+@node Checking New Groups
+@subsection Checking New Groups
+
+Gnus normally determines whether a group is new or not by comparing the
+list of groups from the active file(s) with the lists of subscribed and
+dead groups. This isn't a particularly fast method. If
+@code{gnus-check-new-newsgroups} is @code{ask-server}, Gnus will ask the
+server for new groups since the last time. This is both faster and
+cheaper. This also means that you can get rid of the list of killed
+groups altogether, so you may set @code{gnus-save-killed-list} to
+@code{nil}, which will save time both at startup, at exit, and all over.
+Saves disk space, too. Why isn't this the default, then?
+Unfortunately, not all servers support this command.
+
+I bet I know what you're thinking now: How do I find out whether my
+server supports @code{ask-server}? No? Good, because I don't have a
+fail-safe answer. I would suggest just setting this variable to
+@code{ask-server} and see whether any new groups appear within the next
+few days. If any do, then it works. If none do, then it doesn't
+work. I could write a function to make Gnus guess whether the server
+supports @code{ask-server}, but it would just be a guess. So I won't.
+You could @code{telnet} to the server and say @code{HELP} and see
+whether it lists @samp{NEWGROUPS} among the commands it understands. If
+it does, then it might work. (But there are servers that lists
+@samp{NEWGROUPS} without supporting the function properly.)
+
+This variable can also be a list of select methods. If so, Gnus will
+issue an @code{ask-server} command to each of the select methods, and
+subscribe them (or not) using the normal methods. This might be handy
+if you are monitoring a few servers for new groups. A side effect is
+that startup will take much longer, so you can meditate while waiting.
+Use the mantra ``dingnusdingnusdingnus'' to achieve permanent bliss.

@vindex gnus-subscribe-newsgroup-method

+@node Filtering New Groups
+@subsection Filtering New Groups
+
A nice and portable way to control which new newsgroups should be
subscribed (or ignored) is to put an @dfn{options} line at the start of
the @file{.newsrc} file. Here's an example:
@code{nnfolder}, @code{nnmbox}, and @code{nnmh}) subscribed. If you
don't like that, just set this variable to @code{nil}.

Changing the server is pretty easy, right? You just change

+@file{site-init} files with Gnus stuff. Gnus will also check for files

+@file{~/.gnus}, it will look for @file{~/.gnus.elc}, @file{~/.gnus.el},

@node Auto Save
In any case, if you use @code{some} or @code{nil}, you should definitely
kill all groups that you aren't interested in to speed things up.

-
-The first element is the @dfn{group name}, as Gnus knows the group,
-anyway. The second element is the @dfn{subscription level}, which
-normally is a small integer. The third element is a list of ranges of
-read articles. The fourth element is a list of lists of article marks
-of various kinds. The fifth element is the select method (or virtual
-server, if you like). The sixth element is a list of @dfn{group
-parameters}, which is what this section is about.
-
-Any of the last three elements may be missing if they are not required.
-In fact, the vast majority of groups will normally only have the first
-three elements, which saves quite a lot of cons cells.

+@subsection Server Variables
+
+One sticky point when defining variables (both on backends and in Emacs

+variables when the definition of the variables is being loaded. If you
+change the "base" variable after the variables have been loaded, you
+won't change the "derived" variables.
+
+This typically affects directory and file variables. For instance,
+@code{nnml-directory} is @file{~/Mail/} by default, and all @code{nnml}
+directory variables are initialized from that variable, so
+@code{nnml-active-file} will be @file{~/Mail/active}. If you define a
+new virtual @code{nnml} server, it will @emph{not} suffice to set just
+@code{nnml-directory}---you have to explicitly set all the file
+variables to be what you want them to be. For a complete list of

+manual, but here's an example @code{nnml} definition:
+

@item Lines, Chars
These two headers use different match types: @code{<}, @code{>},
-@code{=}, @code{>=} and @code{<=}.
+@code{=}, @code{>=} and @code{<=}. When matching on @code{Lines}, be
+careful because some backends (like @code{nndir}) do not generate
+@code{Lines} header, so every article ends up being marked as having 0
+lines. This can lead to strange results if you happen to lower score of
+the articles with few lines.
@item Date
For the Date header we have three kinda silly match types:
header uses.
@item Followup
-This match key will add a score entry on all articles that followup to
-some author. Uses the same match types as the @code{From} header uses.
+This match key is somewhat special, in that it will match the
+@code{From} header, and affect the score of not only the matching
+articles, but also all followups to the matching articles. This allows
+you e.g. increase the score of followups to your own articles, or
+decrease the score of followups to the articles of some known
+trouble-maker. Uses the same match types as the @code{From} header
+uses.
@item Thread
-This match key will add a score entry on all articles that are part of
-a thread. Uses the same match types as the @code{References} header
-uses.
+This match key works along the same lines as the @code{Followup} match
+key. If you say that you want to score on a (sub-)thread that is
+started by an article with a @code{Message-ID} @var{X}, then you add a
+@samp{thread} match. This will add a new @samp{thread} match for each
+article that has @var{X} in its @code{References} header. (These new
+@samp{thread} matches will use the @code{Message-ID}s of these matching
+articles.) This will ensure that you can raise/lower the score of an
+entire thread, even though some articles in the thread may not have
+complete @code{References} headers. Note that using this may lead to
+undeterministic scores of the articles in the thread.

+The clue of this entry should be any number of files. These files will
not be loaded, even though they would normally be so, for some reason or

That means that that subject will get a score of ten times -1, which
should be, unless I'm much mistaken, -10.
+If you have auto-expirable (mail) groups (@pxref{Expiring Mail}), all
+the read articles will be marked with the @samp{E} mark. This'll
+probably make adaptive scoring slightly impossible, so auto-expiring and
+adaptive scoring doesn't really mix very well.
+
The headers you can score on are @code{from}, @code{subject},
@code{message-id}, @code{references}, @code{xref}, @code{lines},
@code{chars} and @code{date}. In addition, you can score on
@code{gnus-psychoanalyze-user} command to go through the rules and see
what words you like and what words you don't like. Or perhaps not.
+Note that the adaptive word scoring thing is highly experimental and is
+likely to change in the future. Initial impressions seem to indicate
