    KXStudio is and always will be a free and open-source project to everyone.<br/>
    Donations help ensure that developers have the needed enthusiasm and motivation to keep working on the project.<br/>
    Just because we're open-source doesn't mean we're allergic to money. ;)

    So far the KXStudio project has received <?php echo number_format($GLOBALS['total_ever'], 2); ?>&euro; in donations.<br/>
    The biggest donation ever made was on <?php echo $GLOBALS['biggest_donation_date']; ?>, with a value of <?php echo number_format($GLOBALS['biggest_donation_value'], 2); ?>&euro;.<br/>
    Thank you very much for your generosity!
