You can also make Gnus prompt you interactively for the name of an
@sc{nntp} server. If you give a non-numerical prefix to @code{gnus}
(i.e., @kbd{C-u M-x gnus}), Gnus will let you choose between the servers
in the @code{gnus-secondary-servers} list (if any). You can also just

@code{(ding)} form, but who cares?
+@item 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
+the group name (of course). Style elements in this group parameter will
+take precedence over the ones found in @code{gnus-posting-styles}.
+
+For instance, if you want a funky name and signature in this group only,
+instead of hacking @code{gnus-posting-styles}, you could put something
+like this in the group parameters:
+
+@example

+ (name "Funky Name")

thread should be sorted before the other. Note that sorting really is

+@vindex gnus-unbuttonized-mime-types

+@item gnus-article-mime-part-function

@code{mouse-face} specs---you can say @samp{%3(hello%)} to have
@samp{hello} mouse-highlighted with @code{gnus-mouse-face-3}.

+@code{gnus-balloon-face-*} variables should be either strings or
+symbols naming functions that return a string. Under @code{balloon-help-mode},
