I browsed google for said method, and ended up finding a nifty code bit to create this method, but not the actual method. Did I miss something in the videos?

string.tr('`~!@#$%^&*()-=_+[]{}|\:";\'<>?,./', '')

6,233 PointsThat works. Just was not expecting the Extra Credit to involve foreign code(foreign to me, at least). I'll know to consider all options for next time. Thanks!
