YPress is a yellow pages system based on WordPress. It is featured with a CMS theme and some plugins. We never change core codes. So asite using YPress can be updated whenever a new version of WordPress is existed. I still move on it. Hopefully, it has been released on September 2011.

Baozi Online Community April 2008 – December 2008
The project is about that we will develop an online community which includes SNS site (Like Facebook), Information site (Like Craigslist). The people who the website is for are mainly college students. Though we failed at last, we learn a lot of stuff.
We have detailed plan both in brain and plan books. If someone wants to invest us, we are able to restart this project.
