Up to now the translated "not for commercial use"-string seems to have been implemented for only the following languages:
Dutch, Estonian, German, Italian, Latvian, Macedonian, Romanian, Russian, Slovakian, Swedish and Turkish.
Though translated strings in the following languages have been made available by users for (quite) some time allready, still the English text is shown in BS.Player Free!
Arabic
Portuguese Brazilian
Bulgarian (Note: not English but Estonian is shown instead!!)
Chinese
Czech
French
Hebrew
Japanese
Polish
Spanish
Uzbek
Croatian/Serbian/Bosnia Herzegovina/Montenegro
This doesn't seem very rewarding towards those users who provided these translations.
Also it surely isn't an invitation for and it won't help in case of any future requests!
