Thank you very much @Nicolas. Your solve small dose of happiness.

This listing is over two years old now - just want to know if it still works in the most recent copy of Hikashowp and if the below is the correct format for city and the country?

<?php
echo str_replace('<br/>',"\n",JText::sprintf(
'HIKA_USER_ACCOUNT_ADMIN_NOTIFICATION_BODY',
$data->name,
$data->username,
$data->user_data->city;
$data->user_data->country;
HIKASHOP_LIVE
));

Thanks!
