I've got some advice: only Wifi with people you trust, since people can hack on the Nintendo DS some people will break your Animal Crossing Wild World game. I don't know why people do it. Most people on TBT are very nice, but some of those hackers have come to TBT. I'm not trying to scare you, I just wanna inform you so you don't end up like kenziegirl...
I'm not calling Lobo a hacker if anybody thinks that I am, I'm sure he's a good person.
