Hi, I see a Mario Kart Wii wiki's in the making, eh? I like the idea. I could certainly help you guys out with the logo. Just a few questions: first of all, what is the maximum size it can be, and second: what elements would you like to see in it? If you'd like me to pick that, no problem, but perhaps there's something you'd like to see. By the way, I work in Photoshop and when needed Illustrator.
