Translation of inept in Spanish

I want to work on the country specific terms first, then do a revision of the words that we have entered so far... please give me a few days to finish it. However, I may need to contact you over the weekend, depending on my progress.
I'm quite tired too by now. So, if it doesn't work just drop me an email and I'll see it first thing in the morning. I wanted to add new words to the dictionary however the other issues kept me more busy than I have imagined.
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.
