According to this, Nintendo has made a legal effort to make US fansite Friendcodes.com drop its logo and domain. According to the site:
Basically Nintendo is "asking" us to remove the site files that are infringing the copyright (such as the logo, which contains the word "friendcodes"), and to drop the domain name for the same reason. [The site's owner,] Corey just responded to the emails tonight, and is going to talk to a NOA rep. (hopefully) Monday over the phone. But honestly, it looks bad. They've been sending the emails for almost a month now with no response, so they're very serious about it right now. We're still talking about what to do, but it looks like we will have to shut down the site temporarily, until it all gets worked out. Of course, if it works out Nintendo's way, we'll be closed down permanently. Naturally, we're going to try and keep that from happening, but like I said, it doesn't look good.
Nice. You crush those kids, Nintendo. Crush them good.
