Two, yes that's pretty cool, but really, is it a topic for discussion?
And three, if it's really bugging you, thaboss GUESSES you could email an admin (support@armorgames.com) and interrupt his VERY busy schedule of making a whole new and better site for the benefit of all the users to notify him of one tiny little mistake that hasn't bothered anyone or even been noticed/cared about by anyone other than YOU.
A misspelling seems too picky of a mistake to be warranting a fix from the administrators. They are busy working on ArmorGames3, so any minor to moderate issue with ArmorGames can be tossed aside.
