Sometimes I Wii myself…

Only because I don't have anyone to Wii with. I just got my console online today. I thought that I'd have to buy some sort of USB WiFi thing until one of Andreas's coworkers clued us in. Now I'm online, but still a little clueless as to what to do when it comes to interacting with other people? Messaging, maybe? How does one arrange a Wii date to play tennis or whatever? Feel free to enlighten me.

Here's my code, in case that's helpful.
