If you recall how to subscribe to servers (see Finding the News)
you will remember that
gnus-select-method let you write a definition in Emacs Lisp of
what servers you want to see when you start up. The alternate
approach is to use foreign servers and groups. “Foreign” here means
they are not coming from the select methods. All foreign server
configuration and subscriptions are stored only in the
Below are some group mode commands for making and editing general foreign
groups, as well as commands to ease the creation of a few
special-purpose groups. All these commands insert the newly created
groups under point—
gnus-subscribe-newsgroup-method is not
Changes from the group editing commands are stored in
gnus-startup-file). An alternative is the
gnus-parameters, See Group Parameters.
Make a new group (
gnus-group-make-group). Gnus will prompt you
for a name, a method and possibly an address. For an easier way
to subscribe to NNTP groups (see Browse Foreign Server).
Make an ephemeral group (
will prompt you for a name, a method and an address.
Rename the current group to something else
gnus-group-rename-group). This is valid only on some
groups—mail groups mostly. This command might very well be quite slow
on some back ends.
Customize the group parameters (

Make a group based on some file or other
gnus-group-make-doc-group). If you give a prefix to this
command, you will be prompted for a file name and a file type.
Currently supported types are

search engine type and the search string. Valid search engine types

Make a group based on an RSS feed
gnus-group-make-rss-group). You will be prompted for an URL.
This function will delete the current group
gnus-group-delete-group). If given a prefix, this function will
actually delete all the articles in the group, and forcibly remove the
group itself from the face of the Earth. Use a prefix only if you are
absolutely sure of what you are doing. This command can’t be used on
read-only groups (like
nntp groups), though.
Make a new, fresh, empty
gnus-group-make-empty-virtual). See Virtual Groups.
Add the current group to an
gnus-group-add-to-virtual). Uses the process/prefix convention.
See Select Methods, for more information on the various select methods.
gnus-activate-foreign-newsgroups is a positive number,
Gnus will check all foreign groups with this level or lower at startup.
This might take quite a while, especially if you subscribe to lots of
groups from different NNTP servers. Also see Group Levels;
gnus-activate-level also affects activation of foreign
The following commands create ephemeral groups. They can be called not only from the Group buffer, but in any Gnus buffer.
Read an ephemeral group on Gmane.org. The articles are downloaded via
HTTP using the URL specified by
Gnus will prompt you for a group name, the start article number and an
the article range.
This command is similar to
the group name and the article number and range are constructed from a
given URL. Supported URL formats include:
Read an Emacs bug report in an ephemeral group. Gnus will prompt for a
bug number. The default is the number at point. The URL is
Read a Debian bug report in an ephemeral group. Analog to
Some of these command are also useful for article buttons, See Article Buttons.
Here is an example:
(require 'gnus-art) (add-to-list 'gnus-button-alist '("#\\([0-9]+\\)\\>" 1 (string-match "\\<emacs\\>" (or gnus-newsgroup-name "")) gnus-read-ephemeral-emacs-bug-group 1))
