Translation of Sonderzug

If I wanted to integrate the above demo on our page, would we need to work with Vocabulix or do you have some other options? Could you send me some samples of other teachers, who integrated this demo?
Anyway, I used these two weeks of break in order to fly to a Spanish speaking country and learn a new language. My friends told me that it was a waste of time but I really insisted. It is educational.
I had to fly to Switzerland very urgently on Sunday, now I am back. Anyway, attached is a newsletter that will be sent to the users of Vocabulix. Should there be any changes, it would be nice.
