Translation of pastoso

I would rather like that you write through the messaging system on this site and not to my private email address. All the info is gathered here online and I would like to keep is this way. It is nothing personal.
Everything in your letter is perfect! Almost no errors and the writing style, very impressive! After this first year in England, you have also improved your vocabulary and the grammar skills.
