我发现楼主很不厚道，居然都是拿着免费下来的东西拿出来再出售，这样的人品不太好。

对于缺乏论坛币又想学点东西的人来说无可厚非,又不是拿免费下载的东西犯罪,也是促进交流嘛

hey, beware of your words, I have no idea that there was a new one posted in here before. I just simply want to share the books which I think is really good. I like this forum, people could exchange the useful tools they got from outside, therefore I have to contribute, right? Anyhow, I know I need to have some coins with me, that's why I am here, but not for any evil purposes. Please understand.
