Mario Kart Channel Guide
Welcome to my guide on the Mario Kart Channel. Here youíll find all the game modes for it.

First is Friends, which pretty much lists your friends, and you can create a room and play around.
Next is Ghost Data, you can do a Ghost Race against anyone in the entire world via Nintendo WFC. Winning a certain amount of races even unlocks certain karts, bikes and characters. It keeps your win loss ratio as well. You can also look at your downloaded Ghost Data for each course. 
Third is Rankings, where you can see Time Trial and Competition rankings. It is set by Friend, Region or Worldwide. You can see if you can beat your friends or even check out the World Championís time.
Last is the Competition, where Nintendo puts out a competition for you to do. Two come out every month. You can send in the data to Nintendo.
You can also get messages from the Mario Kart Channel by selecting it on the Mario Kart Menu.
Hope you liked it!
