Hi Moadib, and welcome!
If you don't speak english very well, I really think you should join the rest of us on IRC.
It really helped me out alot a few years ago, sitting in the WON chatroom and chatting with people. Every time I came across a word I didn't understand a word, I asked the person who said it to explain it. You might come out as an annoying person, but it really helps you learn english.! (thumbsup)
Hope to see you online
