Italki? What's your opinion? Well, I'm using Italki since 3 months ago and, I think that italk is the best form of meet people interested in teach a lenguague that maybe you don't know, so italki is your free teacher online!. I have met many people that is interested in chat with me, in know my lenguage and i have learned many things of they, i don't have the best grammar but now i can read and understand English very well, I was interested in to learn Chinese (basic level) but not in italki and the result was that I learned to write with a Chinese Keyboard. I'm happy for stay here! My level of teach Spanish is considerably high. In General, i like italki, but I think it should have video calling, more teachers (free) and low costs.
