Introduction
A quick and dirty implementation of WhosOnline for MediaWiki. This script was created for a user within the #MediaWiki IRC channel. This version displays the number of Guests and Registered users online.

The timeperiod is presently set to 3600 seconds (1 hour), thus it will show how many unique users have accessed the site within the last hour.

Change $timeperiod to a more appropriate time frame if desired.

Note: Most up to date version of this extension can be found at: http://www.chekmate.org/wiki/index.php/MW:_Whos_Online_Extension

Special Thanks

 * Special thanks to Xypron for adding the table creation functionality within the PHP script.
