I am a native speaker of English, but I also speak German at an intermediate level. I can understand Dutch and I can also write it, albeit with great difficulty.
I was an administrator on Meta and the Simple English Wikipedia, and served the global community as a global rollbacker and a global sysop, between 2012 and 2016. While being mostly retired/inactive due to real life, I still occasionally help as an SWMT member. If you have any questions or concerns about an action I have performed, feel free to leave me a message on my Meta talk page and I will get back to you. Alternatively, you may use e-mail for more private matters.
