Translation of Kartoffelsuppe

I have contacted you 12 months ago to propose your school's inclusion in our language school directory. I wanted to inform you that our site achieved high positions in search engines last month.
I have sent you the translation a few hours ago. I guess it has just arrived. That is very responsible of you. I will have a look at it immediately. If you want to address somebody formally in the singular, you must use 'usted'.
Thanks for the corrections and for accepting my friends request. You are completely right: Spanish grammar is simpler than German grammar. I was just looking for a job where both languages are required.
