OK guys check this out! Master Nite(he made DSi Plaza) (dont know him? Look up his profile!) has created a site called dsiworld.com. Its better than his last site (dsifun.com) because it has a BETA Chatroom with commands like the stuff we have here (kinda :p). It has games, connection to his DSi apps (DSiMac and DSiWindows 2.0). This IS a new site so it will keep transforming and getting new stuff and losing dumb old stuff(theres barely any).
I'll keep you posted! Need more details? Go talk to Master Nite himself!
