Futari, did you try doing a search in QL? Did you try doing a search in Google? Did you try? NO!!! WHY!!! it's so easy.

C'mon people be a little proactive here, there a whole bunch of information in QL in old/new threads/posts but you might want to search first and after doing that; if you don't find it; then ask a question.
