Please give us more details, more specifically about your English improvements whiles staying in MyEC.
As for me, I can say to you now that I've been definitely & gradually improved my written & spoken English ever since I joined here in MEC on February 2010, as I've already described how I tried & learned on one of my blogs, called 'Some dilemmas & future improvements of learning English!'. Now I have more confidence in my English expressions and I am able to see the mistakes of my friend's blog or their comments or their messages. I know I still need to focus on some specific areas where I should try & learn for further improvements.
However, I am so happy what I've gained, how much I've achieved in reaching to the goal so far and also to see myself a certain unexpected ability as enabling myself to express spontaneously in anything & everything whatever I have in mind, for the future English improvements. SO FAR SO GOOD!
Please tell us about your improvements....
