Translation of wolkenlos

I will add a feature to the dictionary builder tool, that marks a word as vulgar. The words that are shown in the tool are words that users did not find in our dictionary and a lot of them are vulgar.
In plural there is no difference between the formal and the colloquial address form. Do you mean that you are using 3rd person singular form for the plural imperative? If so, I will change all entries so far.
I speak a little English. I would be happy to teach you German as well. May I can introduce myself? My name is Jürgen and I live in Dusseldorf. 25 years ago I was born in Mannheim, Germany.
