With Friendster Chinese you can create a Friendster profile all in Chinese. Then when you post comments to your friends, or they post comments to you, they can be in Chinese too. Also messages, shoutouts and bulletins are all in Chinese.
Chinese just may be the most spoken languages in the world today. This was a great move on the part of Friendster. If you speak Chinese and have friends who also speak Chinese you can all sign up and keep in touch in your own language. More languages are coming soon, so if you don't speak Chinese, watch for your language in the future.
