Make a new section under the Nintendo childboards for Console and Handhelds for Wi-fi matches. People could arrange Wi-fi matches and have a blast.I dunno about you guys,but I think this would be a hit.Its just my opinion though...
If you go to "www.wii-friends.net" you can share fc's there, it's an awsome site trust me. Not much to look at but just came out of beta.
