Hello. I am LightandDark2000 (or BlueHypercane761 on Wikimedia Commons). I am a user primarily interested in science and technology-related articles, and I combat vandalism when the need arises. I also engage in cross-wiki editing, usually to update information on data pages or to fight cross-wiki vandals. I am mostly active on en.wiki and Wikimedia Commons, but you will probably find me on other foreign language wikis as well. If I haven't set up my userpage on a Wikimedia Project where my account exists, you will see this page.
