Thank you from Blockly!
Thank you for your kind words about Blockly on your user page and for your translation work. With your background and interests, you'd be a great person to help translate the core language, which we've just added to translatewiki, which will enable children to program entirely in Greek.
The translated puzzle and maze have been up for a long time (I'm way overdue in thanking you).
We've added you to our list of contributors. Please let us know if you prefer to be credited in a different way.
Thanks to the contributions and those of the other Greek translators, Blockly has been entirely translated into Greek! Take a look.
I really cannot thank you enough for helping us enable Greek children and adults to learn programming their native language. We literally could not have done it without you.
