What an incredible video! I really enjoyed it and will be tweeting and posting it on my blog as well! :-)

Thank you for your generosity Elena. I know the teachers and colleagues with whom I work will receive great value from your work on this video. If you have the opportunity to put the PPT into English I would be grateful. But I am mindful of the busy life of a teacher so please only do it if you have the time.
I shall put your website and blog address under the video and use a phrase like: "Used with the permission of the creator Elena Elliniadou". Is that okay with you?
The other thing that you might like to do is to place a Creative Commons License on it which lets other people know that you give permission and how you want to be acknowledged: http://creativecommons.org/
