This widget will total up your posts and comments and work out in pounds(lb) how much paper you have saved by writing online.
Alternatively if you want more options for placement of the widget, you can place this include statement in your theme's files(assuming you are not using sub-domains, if you are you may have to modify the URI path).
<?php include('wp-content/plugins/greenPaper/greenPaper.php'); ?>
In order for this widget to display properly on your website, your theme must be properly constructed (ending of tags etc). If you wish to check you can use the W3c's validator in this link: http://validator.w3.org/.
