Translation of vorstellbar

I'm Ricky. I am learning English at school here in Switzerland and at the same time I am learning Italian. You writing skills are very good. Where did you go on your last vacation? See you next week.
In plural there is no difference between the formal and the colloquial address form. Do you mean that you are using 3rd person singular form for the plural imperative? If so, I will change all entries so far.
Maybe it's just a small mistake but I think that we corrected almost all errors. But I'm not worried anyway, because you already have good language skills. Good luck with your exams tomorrow.
