+Threading is done by looking at the @code{References} headers of the
+articles. In a perfect world, this would be enough to build pretty
+trees, but unfortunately, the @code{References} header is often broken
+or simply missing. Weird news propagation excarcerbates the problem,
+so one has to employ other heuristics to get pleasing results. A
+plethora of approaches exists, as detailed in horrible detail in
+@pxref{Customizing Threading}.
+
+First, a quick overview of the concepts:
+
+@table @dfn
+@item root
+The top-most article in a thread; the first article in the thread.
+
+@item thread
+A tree-like article structure.
+
+@item sub-thread
+A small(er) section of this tree-like structure.
+
+@item loose threads
+Threads often lose their roots due to article expiry, or due to the root
+already having been read in a previous session, and not displayed in the
+summary buffer. We then typically have many sub-threads that really
+belong to one thread, but are without connecting roots. These are
+called loose threads.
+
+@item thread gathering
+An attempt to gather loose threads into bigger threads.
+
+@item sparse threads
+A thread where the missing articles have been ``guessed'' at, and are
+displayed as empty lines in the summary buffer.

+If you are writing a message (mail or news) and suddenly remember that
+you have a steak in the oven (or some pesto in the food processor, you
+craaazy vegetarians), you'll probably wish there was a method to save
+the message you are writing so that you can continue editing it some
+other day, and send it when you feel its finished.
+
+Well, don't worry about it. Whenever you start composing a message of
+some sort using the Gnus mail and post commands, the buffer you get will
+automatically associate to an article in a special @dfn{draft} group.
+If you save the buffer the normal way (@kbd{C-x C-s}, for instance), the
+article will be saved there. (Auto-save files also go to the draft
+group.)
+
+@cindex nndraft
+@vindex nndraft-directory
+The draft group is a special group (which is implemented as an
+@code{nndraft} group, if you absolutely have to know) called
+@samp{nndraft:drafts}. The variable @code{nndraft-directory} says where
+@code{nndraft} is to store its files. What makes this group special is
+that you can't tick any articles in it or mark any articles as
+read---all articles in the group are permanently unread.
+
+If the group doesn't exist, it will be created and you'll be subscribed
+to it. The only way to make it disappear from the Group buffer is to
+unsubscribe it.

-you private mail:

+
+This means that you have to have set up @code{ssh-agent} correctly to
