I would like to see regions and provinces from ALL countries in MarketPress. Not just US, Canada and Australia. It's just not fair.
I'm not one of those guys that ask for something without giving so I've taken the first (and most important) step. I found all those regions and I updated the marketpress-data.php file.
You can get the new one right here: https://github.com/drupin/marketpress-data/blob/master/marketpress-data.php
The regions/provinces were extracted from UberCart (one of the most complete Drupal commerce modules) and I've adapted them to Marketpress.
So in a future update please include those... I didn't update the other files (I bet you don't want to see all MarketPress files in github :stuck_out_tongue: ) but it shouldn't be too much work.
