Hello!
I've playing with OSClass for a few hours, hacking away the code to fix some minor bugs and language strings without gettext, and I noticed one particular thing that would be very helpful for the end-users: a 'default_country' on the language package config file (index.php).
This way admins could set it to the country they're in and end-users wouldn't have to change the always-on

Afghanistan.
Anyways, great little piece of software you have here!

Cheers
