Translation of ausarbeiten

Thanks again for your time. I attached my avatar, it is very similar to the previous one. I have guided the development of the website, and I feel free to share my knowledge with others.
I've also looked at the interface, and found it a good idea to include the colloquial option. Would it be very complicated to add the most important regional check box, like Spain, South America or Central America?
I'm learning German for a year. I do not write well, but I hope to improve soon. This is precisely why I want to make friends on vocabulix. In August I will fly to Berlin, it will be my first time.
