This legacy widget plugin shows the top commentators in your WP site.
ATTENTION: The widget capability of this plugin will be slowly phased out in favour of block support.
The Top Commentators Widget plugin is adapted from Show Top Commentators plugin at Personal Financial Advice, this widget is easier to manage via the control form (no need to edit the PHP file); additional options are also available to make it more flexible. Read the FAQ section on how to customize the widget. Read the Changelog as well as http://webgrrrl.net/tags/tcw for the latest news on this widget.
