My name is David Castor. I am an administrator and bureaucrat at the Swedish Wikipedia. Other language versions are visited primarily to search for material with which to improve the Swedish version. I am best reached at my Swedish user discussion at sv:Användardiskussion:Dcastor. Swedish, Danish, Norwegian and English are prefered languages, but I can propably manage German and Dutch too (my reply will be in Swe/Eng, though).
My pictures uploaded at Wikimedia Commons are available at commons:Category:Images by David Castor.
