There is a space to add friend codes in your profile anyway that only registered users can see. I havn't updated it in a while so a lot of games are missing but if people request it, I will start adding them again.

There is also a "other information" box on the news page which allows you to see people that are available for WiFi games or want to set something up. You can read more how to use this box on our DS Site:
