Uh, races? They would have to change how the game works but if the post was sometime around when the game launched the would probably do it as most wizards wouldn't be accustomed to Wizard101 yet so it's likely a big NO! Sorry; they may include it in their next game.
Now, I certainly think we need more customization options for sure at the beginning at the game, but Races like those in the spiral kinda wouldn't really work. Firstly, they say we are not from the spiral(It is implied that we are from real life) So Spiral Races would contradict the plot to an extent. I wouldn't disagree with humanistic, non-Spiral races such as elves or dwarfs(Would be awesome to play as a dwarf!) Maybe School themed Races as well, but not really Spiral Races. What I think would work better, however, would be permanent Transformation Potions, pretty much allowing you to play as Spiral Races. There could be an extension that allows you to change colors and equipment while transformed.
