My name is Dennis Brown. I've been a Wikipedia editor since September of 2006 and I've been an administrator on the English version of Wikipedia since April of 2012. Most of my editing there tends to be clean up and gnoming, although I have created around 60 articles, and have a couple of GAs, an FA and several DYK articles. If you are interested in more, my user page has a great amount of detail there, look.
If you need to contact me, it's sometimes faster do so on my talk page at the English Wikipedia [1].
