Onto the whole OMG DSITABS SHUTDOWN!!!! thing, it was never shutdown. The Tabs are there. Accounts, Favorites, everything but the community system.
Things have changed. People are playing games everywhere. It's time to throw everything you have into ONE profile. 360, PS3, Steam (PC), and Wii/DS. It's all complicated when you have to tell someone. That's why I am building G/net.
G/net is out, but at the moment... only the 360 is supported. Recent games, your avatar, and status on Xbox Live show up on your profile. Steam runs in a similar fashion. Wii/DS is based on inserting the games name and the friend code. PS3 is... just your username, where are the API's for the darn system?
Onto the Wii/DS friend code system. The idea is to make a search system so people can find people's friend codes for a certain game... or look onto a user's profile. It's a pain to get ALL of the current games the Nintendo Wifi network into a database.
So, register on G/net today. (All features are not complete, some are launching soon).

Also, as an added note... I develop for DSiHub as well.
