Having recently discovered an awesome website called Mii Plaza, my Mii count has gone from 10 to 25.  That's fifteen Miis!  Mii Plaza shows pictures of Miis created by users, and I must say it's quite good.  Some of the Miis I've cranked out with the help of this site are Miyamoto, Mario, Dr. Phil, Rocky Balboa, a Rabbid, and many more!  Check it out and see what you think.  Awesome, no?
