Are you interested in the October Challenge? Hosnestely, I don't feel it worth. Al least, does not worth as the World Cup Challenge. In this last one, period of the challenge was 2 months and the prize was 400 ITC! Win 200 ITC is good, but, c'mon, you can win the same amount just indicating some friend to be a student here at Italki. I think these challenge should have a better prize like 400 ITC to worth the risk of not completing the 25 lessons. What do you think about? Are you going to take this Challenge?
