INSTRUCTIONS

  This script is used to include information about your board from
  pages outside the forums and to syndicate news about recent
  discussions via RSS. The script can display a list of recent
  discussions (sorted by post time or last post time), a list of
  active users or a collection of general board statistics. The
  script can be called directly via an URL (for RSS), from a PHP
  include command or through the use of Server Side Includes (SSI).

  The scripts behaviour is controlled via variables supplied in the
  URL to the script. The different variables are: action (what to
  output), show (how many topics to display), fid (the ID or ID's of
  the forum(s) to poll for topics), nfid (the ID or ID's of forums
  that should be excluded) and type (output as HTML or RSS). The
  only mandatory variable is action. Possible/default values are:

    action: active (show most recently active topics) (HTML or RSS)
            new (show newest topics) (HTML or RSS)
            online (show users online) (HTML)
            online_full (as above, but includes a full list) (HTML)
            stats (show board statistics) (HTML)

    show:   Any integer value between 1 and 50. This variables is
            ignored for RSS output. The default is 15.

    fid:    One or more forum ID's (comma-separated). If ignored,
            topics from all guest-readable forums will be polled.

    nfid:   One or more forum ID's (comma-separated) that are to be
            excluded. E.g. the ID of a a test forum.

    type:   RSS. Anything else means HTML output.

  Here are some examples using PHP include().

    Show the 15 most recently active topics from all forums:
    include('http://host.com/forums/extern.php?action=active');

    Show the 10 newest topics from forums with ID 5, 6 and 7:
    include('http://host.com/forums/extern.php?action=new&show=10&fid=5,6,7');

    Show users online:
    include('http://host.com/forums/extern.php?action=online');

    Show users online with full listing of users:
    include('http://host.com/forums/extern.php?action=online_full');

    Show board statistics:
    include('http://host.com/forums/extern.php?action=stats');

  Here are some examples using SSI.

    Show the 5 newest topics from forums with ID 11 and 22:
    <!--#include virtual="forums/extern.php?action=new&show=5&fid=11,22" -->

    Show board statistics:
    <!--#include virtual="forums/extern.php?action=stats" -->

  And finally some examples using extern.php to output an RSS 0.91
  feed.

    Output the 15 most recently active topics:
    http://host.com/extern.php?action=active&type=RSS

    Output the 15 newest topics from forum with ID=2:
    http://host.com/extern.php?action=activ … &fid=2

  Below you will find some variables you can edit to tailor the
  scripts behaviour to your needs.
