Since 2003, I've been editing various Wiki pages in the EnglishWikipedia, so as to correct the wrong/misleading information and fill the missing information that I think is important. Most of my contributions are related to Hong Kong, computing and anime/manga. I try to contribute as unbiased as possible. I was once being nominated for adminship, but failed.
I've been spreading Firefox before the creation of Spread Firefox community site. In fact, in the starting of the semester A, 2004, I convinced the Department of Computer Science to install Firefox on the Windows workstations that are open to the CS students. I found that a significant proportion of my classmates is already using Firefox as their default browser. That's really exciting!
Besides spreading Firefox in the real life, I set up a climateprediction.net team named "Spread Firefox" at September 262004. The team is hence known as "[email protected]" for short. Thanks to Robin Monks of MozNews, I was able to have an official website for the team. In less than 2.5 months, the team managed to become the second most productive team (but now being the seventeenth). The power of Firefox community is simply amazing!
