You guys are great.
I really appreciate what you're doing for the people. You are the only webpage that works for free, because Babel and Busuu are very expensive. And all things should be like that. I mean why should you pay for knowledge? I love pages like Wikpedia, like Duloingo. Where the creators don't care about but helping people and spreading something that's really belongs to everyone(Knowledge) Congratulations, keep doing what you do. And never change... :)
