You must remember there isnt (but sometimes is ...) an "offline" for
Gnus. According to the manual "plugged" refers to individual
servers. Some may be online, others not. Are you saying that pressing
"g" for example tries to connect your servers even though they are agent
groups and you are unplugged? 

rambling :

I'm pretty sure the relevance of my reply is limited but allow me to
describe my use of gnus with levels and agent. It might be of some
interest.

Just google in gmane I guess. I was undoubtedly rambling too as I tend
to do when trying to get my head around the finer points of Gnus ;) I
was learning agent in combination with group levels and I still dont
think it works as designed per se .. when groups activate is still a bit
of a mystery to me. i need to sit down and review my settings. But I
guess I got a bit frustrated... The articles are from the 18th March
until the 3rd April or so. 17 days in the Canaries... mmm.. seems like
yeas ago already.

but basically,

I start gnus plugged but with the default "activate" level set to 1. The
only groups I have at level 1 are LOCAL email repos (nnmail) so I can
instantly see root mail etc. I think all local and agentised groups
ought to be configurable for activation even if unplugged. I couldnt get
the right combo of settings to achieve this. "activation" in this case
meaning being visible showing me how many unread I have. Thinking about
this, now I do topic level "fetch" (described below) I could just make
all agentised groups level 1. I need to test that again.

I do that like this:

,----
| C-c m runs the command (lambda nil (interactive) (gnus-agent-toggle-plugged t)
| (gnus 1)), which is an interactive Lisp function.
`----


I do the plugged toggle call because Gnus remembers its plugged state
between invocations : if I quit gnus when its unplugged then calling
(gnus) again starts it unplugged. i think thats a bug tbh. I start it
plugged but with no activation of any "online" groups so that my level 1
groups actually activate and are visible.

My gmail is on level two. To get this I can C-u 2 g OR (and more likely)
I put my cursor on my imap email "topic" line and hit M-g. C-u 2 g would
fetch level 1 too.

I have nntp at level 5. I *could* do C-u 5 g but this would get levels 4
and below too. So instead I tend to M-g on my "news" topic line. Doing
C-u 5 g would fetch levels 5,4,3,2,1.

Now, lets look at agent:-

What I would do (if it worked with my imap setup) is go "plugged", enter
a group and fetch all headers. quit the group back to the summary buffer
and do a J s I think it is. I asked about a setting to automatically get
all the articles and not just the headers into the agent when entering a
plugged group in order to make the J s redundant form the summary
buffer. That done you could go back unplugged and read "offline".

But remember non agent groups are still "online".

Maybe that was of some interest if not directly helping!
