What I do on Wikipedia
Besides being an avid reader of Wikipedia (mostly in English and Chinese), I also do proofreading, e.g. correcting spelling and punctuation mistakes, rolling back vandalism, and adding interlingual links.
I made my very first edit on Wikipedia on September 20, 2003. Wow, it has been a while ago...
