Chinese languages

I just started learning Chinese, the best way for me is collecting useful free learning material online, ‘coz going to class will take me too much time, and the tuition is too expensive for me too. Here is a few links I believe worth checking for self-study:

http://www.chinesetime.cn
http://www.chinese-tools.com
http://www.china-8.com
