After some modification in my forum here :
i notice that there will be an overlap content, between my two sites. so after this post , i would change my blog post into INDONESIAN LANGUAGE, so, although there are some same post, but at least it is in different language, so it will have different audience at the end.
at last, this is my last post in ENGLISH, will see you on our GIS forum
oh yeah, almost forgot, happy INDEPENDENCE DAY for INDONESIA on August 17th
