Hi, I'm Yunshui. I've been on Wikipedia for about 14 years, and am currently an administrator. I've been a member of the site's Arbitration Committee (never again!), and as a hangover of those heady days retain checkuser and oversight permissions; I am also a global renamer.

On Wikipedia
This editor is a volunteer, and is willing to write and maintain encyclopedia articles for free.
I generally spend my time here clearing admin backlogs, helping new users and creating articles on anything that happens to catch my interest; very occasionally I'll try taking something to Good or even Featured status. I'm particularly interested in the fields of martial arts and East Asian history in general (although despite my choice of username, my grasp of East Asian languages is limited to a smattering of words and phrases in Japanese and a few odd bits of Mandarin).
I don't often edit at weekends (it happens, but it's not common). If you ask me something on a Friday, Saturday or Sunday, be prepared to wait until Monday for a response.
