Translation of artimaña

The current situation in Libya is really difficult. I tried to get in contact with acquaintances, but all the phones were not working. I'm really concerned about their well-being. I'll try again later.
Yes, but on the other hand, using full, simple sentences also helps people who are learning the language more than just the short clauses. It is probably a mix of both, but I have not decided yet which ratio is the best for us.
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.
