Hello, I am Wiki13. I'm an administrator on the Dutch Wikipedia and was one in the early days of Wikidata too. Nowadays I'm active as SWMT member, a taskforce to help protect small wikis from vandalism, spam and/or trolling. I'm a global sysop, so you can ask me when something concerns a small wiki without active administrators.
Here on Wikimedia Commons I do various activities like categorizing, patrolling the "Media needing categories" for copyvio's and/or out of scope images and uploading images myself, created by myself or others when I deem them useful for inclusion on Wikimedia Commons. If you have any questions about me or something I did, feel to ask me about on my talk page.
