Nintendo FrienDS (http://www.nintendofriends.net) is a really awesome DS WiFi site where you can make WiFi buds, set up random matches, chat during-game on their IRC, post on their DS-dedicated forums, and more!

It's really awesome. If you play DS on WiFi, I highly reccomend this site.

EDIT: The site does require registration before you can use their services, and registration requires email confirmation, but they don't send any spam email.

cool nice find

too bad with the psp u have a wifi browser that works a whole lot better than the DS wifi. Btw, pretty much no one knows that the DS has a microphone because they don't use it.

no that's not true because it says mic next to the microphone dip****

Okay, if by "wifi browser", you're refering to that piece of crap Wipeout hack, then you have issues. That browser sucked total ass. The PSP didn't even have the memory to run it properly...If Nintendo ever releases a web browser, at least they'll implement enough clever coding to make it work properly. (Doubt they will, though)

And you'd have to be a complete dip**** not to notice the obvious "mic" letters printed on the suface of the console, as Guess_Who mentioned. And it is used much more than you think. Mariokart used it, WarioWare Touched used it, and Nintendogs used it, all of which are somewhat popular games.

Not to mention the upcoming "DSpeak" software will use it for voice communication on WiFi. w00t! :D
