Begining with Italki I'm a new user of Italki and I'm surprised with the quantity and quality of the community. I'm starting with English learning and I think it is very important exchange words with native speakers. I will like learn English to travel without limits to comunicate. The major difficult for me is find the words to express all i want to say, then finally write or speak basic things. Regards
