Thank you!

WOW! Really am happy to hear that! But please consider that Google App Engine and Google Code is blocked on Iran (and the link you've provided is blocked for me due Google sanctions). Please consider to migrating to a more freedom place such as Github if is possible :)
Thank you for pointing that out. Blockly can run entirely client-side, but, as you point out, you do need to get the source code. I'm going to talk to the Google Code team to ask if Google is blocking Iran (I thought it was the other way around) and with my tech lead about a github mirror (although I guess I don't need anyone's permission because it's open source). I'll get back to you soon.
