Translation of fondue in Spanish-English

The script I am writing will shuffle the 1.5 million words and it will detect if too many words are from the same user. And if an entry is too long, I will skip it and rely on the sentences that we can hopefully make up together.
It is good if you have previously practiced only Spanish, which also shows that you are very good at other languages, and still can learn many things. I hope I'll learn it soon and practice.
I am glad that you accepted my offer. I would like to write letters and emails in English and if you want you can write back to me in German. I want to correct your German and so we will both get better.
