DO NOT pay your attention to these peoples! there always be such morons. You are doing GREAT! i'm watching your videos since beginning of december, and i honestly can say - you are the best teacher i ever saw. right now i'm trying to improve my english just to get a coaching session with you. Your tutorials are helpfull and posts are always on time. I recomend your blog to all my friends already. so it's just a matter of time, when impact of these trolls would be unseenable.
P.S. sry for my english, i'm still working to improve it.
Wish you all the best!
