# IM tools cannot save the answers & resolutions, so new comers will ask basic questions again and again coz they can not search the discuss in the forum.
# Cocos2d-iphone has a official IRC channel, http://webchat.freenode.net/?channels=cocos2d-iphone, but seldom people are still using it.
# Time zone. Most of developers here are in European or America timezone, so when they’re working, we’re sleeping # I prefer gtalk group, but this service is blocked by Chinese government, only seldom of us who has bought VPN can use them.
Perhaps I must try to set VPN on the router at first.
