;; gnus-registry.el intercepts article respooling, moving, deleting,

;; you, submit a bug report and I'll be glad to fix it. It needs
-;; documentation in the manual (also on my to-do list).
+;; better documentation in the manual (also on my to-do list).
+
+;; If you want to track recipients (and you should to make the
+;; gnus-registry splitting work better), you need the To and Cc
+;; headers collected by Gnus. Note that in more recent Gnus versions
+;; this is already the case: look at `gnus-extra-headers' to be sure.
+
+;; ;;; you may also want Gcc Newsgroups Keywords X-Face
+;; (add-to-list 'gnus-extra-headers 'To)
+;; (add-to-list 'gnus-extra-headers 'Cc)
+;; (setq nnmail-extra-headers gnus-extra-headers)
;; Put this in your startup file (~/.gnus.el for instance) or use Customize:
;; You should also consider using the nnregistry backend to look up
;; articles. See the Gnus manual for more information.
+;; Finally, you can put %uM in your summary line format to show the
+;; registry marks if you do this:
+
+;; show the marks as single characters (see the :char property in
+;; `gnus-registry-marks'):
+;; (defalias 'gnus-user-format-function-M 'gnus-registry-article-marks-to-chars)
