+@vindex gnus-parameters-case-fold-search
+By default, whether comparing the group name and one of those regexps
+specified in @code{gnus-parameters} is done in a case-sensitive manner
+or a case-insensitive manner depends on the value of
+@code{case-fold-search} at the time when the comparison is done. The
+value of @code{case-fold-search} is typically @code{t}; it means, for
+example, the element @code{("INBOX\\.FOO" (total-expire . t))} might be
+applied to both the @samp{INBOX.FOO} group and the @samp{INBOX.foo}
+group. If you want to make those regexps always case-sensitive, set the
+value of the @code{gnus-parameters-case-fold-search} variable to
+@code{nil}. Otherwise, set it to @code{t} if you want to compare them
+always in a case-insensitive manner.
+
+You can define different sorting to different groups via
+@code{gnus-parameters}. Here is an example to sort an @acronym{NNTP}
+group by subject and an @acronym{RSS} group by reverse date to see the
+latest news at the top. In this example, the first group is the Debian
+daily news group @code{gmane.linux.debian.user.news} from
+news.gmane.org. The @acronym{RSS} group corresponds to the Debian
+weekly news RSS feed
+@url{http://packages.debian.org/unstable/newpkg_main.en.rdf},

-The Agent works with any Gnus back end, including nnimap. However,
-since there are some conceptual differences between @acronym{NNTP} and
-@acronym{IMAP}, this section (should) provide you with some information to
-make Gnus Agent work smoother as a @acronym{IMAP} Disconnected Mode client.
+The Agent works with any Gnus back end including those, such as
+nnimap, that store flags (read, ticked, etc) on the server. Sadly,
+the Agent does not actually know which backends keep their flags in
+the backend server rather than in @file{.newsrc}. This means that the
+Agent, while unplugged or disconnected, will always record all changes
+to the flags in its own files.
-The first thing to keep in mind is that all flags (read, ticked, etc)
-are kept on the @acronym{IMAP} server, rather than in @file{.newsrc} as is the
-case for nntp. Thus Gnus need to remember flag changes when
-disconnected, and synchronize these flags when you plug back in.
-
-Gnus keeps track of flag changes when reading nnimap groups under the
-Agent. When you plug back in, Gnus will check if you have any changed
-any flags and ask if you wish to synchronize these with the server.
