The command `gnus-no-server' will likely do what you want.

Do it like you do with Emacs, don't kill it.

(defun gnus-switch-to-group-buffer ()
  (interactive)
  (if (gnus-alive-p)
      (switch-to-buffer gnus-group-buffer)

IIRC this will only stop the primary select method.

In addition to setting this to nil, I also set the levels ('S l' in the
Group buffer) of all the groups to 7 to achieve this.

By default it will only activate groups at levels 1 and 2. In my case,
anyway, that only connects to the nndraft server.

Level 7 is considered "unsubscribed", so that might cause some issues.
Try level 3?

I've used this strategy for some years and level 5 works
perfectly for me.  When I want to read a level 5 group, I
position to the group and M-1 g does it "on demand."

Only my INBOX is level 1 (I fetch from gmail).

It appears that much of the time was spent on fetching and parsing rss
feeds. I am using (setq nnrss-use-local t) which I expected to be much
faster, but that gnus is still very slow.

Some of you suggested to change the level of subscription to a higher
number. What are the implications of this change? I mainly am interested
in getting the list of new news of all subscribed groups about once a
day.

Which is why I switched to elfeed for rss feeds.  I would prefer to use

There will be a newly-implemented backend for Atom landing in Gnus
before too long, and I think we're hoping to make it work for RSS as
well. I'll try to make sure that it does better with situations like
this. I also find nnrss too slow for practical use, and hope it's
something fixable.

My bad!  It's a customization I have in my .gnus.el file:

--8<---------------cut here---------------start------------->8---
  (defun esf/gnus-agent-plugged ()
    (gnus-group-send-queue))
  (add-hook 'gnus-agent-plugged-hook 'esf/gnus-agent-plugged)
--8<---------------cut here---------------end--------------->8---

You could probably simply add 'gnus-group-send-queue to the hook without
defining an extra function.

Smart! Thanks! (I have that with other important folders, but it didn't
occur to me to put nndraft:queue there.)

Thanks again for "J S"!

As for toggling: my queued messages are not automagically sent when I
toggle to on-line ("plugged"). Do you know if this hinges on some
setting somewhere? Any hints? It would be A Good Thing(tm) to have.

Re: Inhibiting gnus-get-new-news at startup

[Eric S Fraga]

I do the same: starting unplugged.  This works well as I use nnml to
store my emails and have all nttp groups under control of the agent.

To avoid forgetting about queued emails, I have my queue group at level
1 and it's the first group in the Group buffer view.

To manually send queued emails, it's "J S" and you don't have to be in
the queue group for this: it works from the Group buffer.  But, for me,
when I toggle to plugged status, all of my queued emails are sent.  If
you wish to remain unplugged, J S will send them regardless.

I usually start Gnus with M-x gnus-unplugged when I don't want to
contact any servers at startup.

The drawback is that once Gnus is up, it's important to run
gnus-agent-toggle-plugged (keys "J J") from the Groups menu. That will
put Gnus back in normal mode (without downloading new messages). If one
doesn't toggle back, Gnus will remain in off-line mode, which includes
just queueing outgoing mail in nndraft:queue, and they will _NOT_ be
sent automagically when one toggles back to on-line mode. One has to do
that manually (i.e., go to that folder an issue "D S"
(send-all-messages, or some such)), which is very easy to forget, in
which case one's messages will remain unsent until the dusk of eternity.

Inhibiting gnus-get-new-news at startup

[Husain Alshehhi]

Hello,

When gnus starts (M-x gnus), it automatically get new news. This is a
reasonable default. But when I start gnus multiple times to look up a
message, I have to wait few seconds for it to start. Is there a way to
prevent gnus to get new news at startup time, and only do it manually?
