I'm Caseman, in normal life I'm called Kees.
I live in the Netherlands and have been quite active on the nl:Wikipedia since about mid 2004. My main contributions there are in the field of Astronomy, I've reorganised the constellations and created articles for all named stars, among others. I've also contributed on electronic music, technology and anything else I know something about that was not mentioned yet in articles I've encountered. I don't know what my contributions here will be, although I already fixed some errors in the Suhail al Muhlif article.
I don't know yet if I will be using this account very often, so if you want to contact me safest will be to go to my Dutch discussion ("overleg") page.
