+* Contacts
+The majority of my online communication is done via e-mail.  Over the
+years---especially on mailing lists---it's easy to accumulate a lot of
+contacts, and it's easy to forget who people are.  So, I need the ability to
+not only store names and e-mail addresses (and auto-complete them!), but
+also notes about the person, so that I can remember who they are or other
+useful information about them.
+
+Emacs comes with BBDB---the "Insidious" Big Brother Database---which keeps a
+database of contacts.  I won't pretend that I know how to use it very well,
+but I'll do by best to learn.
+
+#+BEGIN_SRC emacs-lisp
+  (bbdb-initialize 'gnus 'message)
+
+  ;; this is the key for fixing a brokern BBDB3+Gnus integration
+  (setq bbdb-mua-update-interactive-p
+        '(query . create))
+#+END_SRC
+
+In order to build a comprehensive database, I want contacts to be added with
+ease; en masse if need be.
+
+#+BEGIN_SRC emacs-lisp
+  (bbdb-mua-auto-update-init 'gnus 'message)
+
+  ;; return more than just the first address of a message
+  (setq bbdb-message-all-addresses t)
+#+END_SRC
+
+BBDB displays a window ("popup") when adding/editing an entry, or visiting
+articles with known entries, from Gnus (for any MUA it's initialized for,
+for that matter).  The default size shares window space evenly with all
+others---far too large.
+
+#+BEGIN_SRC emacs-lisp
+  (setq bbdb-pop-up-window-size     0.15
+        bbdb-mua-pop-up-window-size 0.15)

 * Command Line
 I generally invoke Gnus in a fresh Emacs process, for various reasons that I
 won't get into here right now.  To make this a bit easier, I add a =gnus=
