beginner splitting mail

[Steven Arntson]

Hi, I'm a gnus beginner, trying to learn mail splitting. I've gotten
nowhere, and am feeling defeated. What I have as a group buffer is what
I got by default:

       0: nnmbox:mail.misc
       2: nndraft:drafts
      67: nnfolder+archive:sent.2014-06
      72: nnfolder+archive:sent.2014-05
      96: nnfolder+archive:sent.2014-04
      21: nnrss:Charles Mudede
      86: gwene.com.nytimes.services.xml.rss.nyt.books
      67: gwene.com.nytimes.services.xml.rss.nyt.science
    2240: gwene.org.emacsen.planet
    (... etc, much more, edited out ...)

What I'd like is:

     3: inbox
     2: drafts
   523: sentmail
    43: blogs
     1: emacs-related
    23: music-related

I've tried to learn about changing how things look, but when someone
says, "Regexp %//.b %" I'm lost! (I /am/ trying to learn about regexp,
BTW, but it's early days.)

Thank you so much for any help. Here's my pitiful attempt at mail
splitting from my .gnus.el, which has had no observable effect on my
group buffer:

;; splitting mail
(setq nnmail-split-methods
       '(("emacs" "^From:.*emacs")
         ("sent.mail" "^From:.*stevenarntson.com)
         ("mail.misc" "")))

Best,
-Steven Arntson
