If you read lots and lots of groups, it might be convenient to group them hierarchically according to topics. You put your Emacs groups over here, your sex groups over there, and the rest (what, two groups or so?) you put in some misc section that you never bother with anyway. You can even group the Emacs sex groups as a sub-topic to either the Emacs groups or the sex groups—or both! Go wild!
Here’s an example:
Gnus
Emacs -- I wuw it!
3: comp.emacs
2: alt.religion.emacs
Naughty Emacs
452: alt.sex.emacs
0: comp.talk.emacs.recovery
Misc
8: comp.binaries.fractals
13: comp.sources.unix
To get this fab functionality you simply turn on (ooh!) the
gnus-topic minor mode—type t in the group buffer. (This
is a toggling command.)
Go ahead, just try it. I’ll still be here when you get back. La de dum… Nice tune, that… la la la… What, you’re back? Yes, and now press l. There. All your groups are now listed under ‘misc’. Doesn’t that make you feel all warm and fuzzy? Hot and bothered?
If you want this permanently enabled, you should add that minor mode to the hook for the group mode. Put the following line in your ~/.gnus.el file:
(add-hook 'gnus-group-mode-hook 'gnus-topic-mode)
