Howdy - I am ShakataGaNai (SGN), it is a misspelling of Shikata ga nai. I am one of zee tech monkeys around these here parts. You may notice me do things I shouldn't be able to do (Like be a 'crat even though it isn't in the logs). It is because I'm in the database changing things. Kinda like the cat in that scene in the Matrix where Keanu Reeves gives his signature "Whoa".
