Okay, so I made an account, I THOUGHT I had chosen a deer name, but it doesn't work. And when playing the game and I go to Options, and I TRY logging in, no matter how many times, it will not allow me to log on. Help, please?

(Also, what does it mean when you get a nuzzle? IT says I currently have five nuzzles..... >.>
ALSO, why do a whole lot of deer sleep in the game?)
