you can download it at http://travel-junkie.com/sql.txt

rename the file to sql.php and open the file up in your favorite text editor. close to the top you’ll see an array $groups. add or modify that array, then upload the script to your server root. navigate to http://your-site.com/sql.php, fill in the data and hit enter.

please note that on my local server the script could only handle about 150 groups at a time, before the script timed out…
