Translation of vogelfrei

In the meantime I am listening to some Spanish CDs. They are intended for the car, but no one can tell you when to listen to it, how many times and how often. Please understand that I work a lot.
As promised, I am sending you in the attachment a (very) little overview of some applications we created on Vocabulix. Please send me also some infos about your activities. When would be the best time to talk?
Thanks for the tip: We will add a lesson on colours! About the topical lessons around the home: Do you have specific words that you think should be added? It will take a while until we upload the new version.
