Translation of Rücktrittbremse

I arrived there but could not find a hotel immediately, so that I took my luggage with me. I know that this is very provocative to thiefs. One should not walk on the street with a big backpack.
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?
I will start working on it next week. You can also have a look at our site and give me some feedbacks. You know Spanish better than I do. so please be patient with our questions. I would really like to help.
