If you're looking for a partner for language exchange, you might be able to find someone on one of the following sites;
Language Exchange Sites
Voice chat and Text Chat available here.
http://www.worldia.net/ (Mostly Japanese)
This is a site with a lot of people trying to help each other learn various languages. There are professional teachers as well as just ordinary people looking for pen pals.
Well this was originally a Korean website sort of like Myspace, as you can read in this article
(I remember seeing Kim Jae Won using cyworld in the Kdrama Wonderful Life.)
The US version http://us.cyworld.com/ has a lot of people from throughout Asia.
Tencent QQ a.k.a. QQ
This is an instant messenger program just like yahoo or MSN except it's Chinese based and orientated. There is an English language version but all links direct to the associated Chinese website so you will need to know some Chinese in order to use it. It is actually a good way to learn the language as people will add you to their buddy list and then expect you to know their language (as you should if you're going to be using this program) But it is a very good way to make friends overseas and get a language exchange partner.
The one problem with using QQ is that the Hanzi tend not to display properly. This can be solved by downloading a program called AppLocale, which allows you to open non unicode programs.

Japanese and English blogging site.
(More Will Be Added Later! ^^)
I can't speak for anyone else but I think it's is quite helpful to do a little background reading on the language you wish you learn. It you are able to form an understanding of something then you should also be able to learn it more easily.
This first part of suggested reading, deals with the various scripts used for writing the various languages.
Simplified Chinese Characters
Traditional Chinese Characters
N/I/SS/J, I'm on 30/64 of the long drama! ♥
