UPDATE: We're go on the new system that requires registration to, well, to do almost anything fun on MiiPlaza.net. You can now register with or without a Wii Console Code, and you can also change your email address. We also now require confirmation on the email address to avoid those nasty typo's people were producing.
We should see a cut back in the amount of spam on Miis, and a lot less anonymous trashing. We hope this improves the community and encourages it to grow. Now we've got to get to work on deleting all that spam and providing the more usual updates... and oh, that 10,000 Mii contest... you know the drill, keep 'em coming and we'll have some great prizes to announce shortly.
P.S. If anyone knows where to get our hands on a Wii that isn't eBay, that information would be very helpful. Thanks.
