Some articles (like this one) are in digest format.  An article is in
digest format if it contains a sequence of messages, each with their
own headers.  Often, nn can split a digest and present each subject
as a separate item on a menu.  In order for nn to be able to split a
digest, each sub-message must have a Subject header and either a Date
or From header, i.e., each message must contain at least...

 Date:
 Subject:

or...

 From:
 Subject:


Any other headers are fine but it must contain at least either of the
above pairs of headers.  So, for example, the following will work:

 Date:
 From:
 Subject:

Usually nn's default is to automatically split a digest (but your
system administrator may have configured it differently on your
system).  You can control the default behavior by setting the split
variable in one of your init files such as init.variables.

set split off  #On the menu, present a digest as a single article
set split on   #On the menu, present each digest sub-message as a menu item

I prefer `set split off' because then the article only takes up one
line on the menu.  If you are interested in it, you can select it and
then, when you are reading it, you can split it by typing G%.  Once a
digest is split, you can read, respond to, print, and save individual
digest items.
