Ooh, that. I didn't like the connotations associated with "Demon Duck." It sound entirely too malignant (sorry, Malignus), and I just don't view myself as a very spiteful, angry, negative person; I'd hate for others to view me that way.
Don't you dare say anything along the lines of "too late." But my name change listed here occured several days/weeks after the change happened, because I forgot to until prompted by the listing of SmartyPants' name change. That is all.
