In case the information would be of help to the Moderators, I am French Active, Greek Passive, Chinese ambidextrous and Japanese proficient...
Umm, thanks for sharing.
As to your request, Yabb SE is available in English (US, Canadian), English (UK), Malaysian. German, Dutch, Chinese, Finnish, Thai, Portuguese, Portuguese (Brazil), Vietnamese, French, Spanish, Norwegian, Russian, Swedish and Polish, so buttons in any of those languages are apt to show up. Sorry there's no Greek.
