I have lab and friends. I agree, lack of things to do after a while. I too, attend agility competitions. I have done the chat thing once. ( with myself ) on my friends game dauchie and friends. U just put the DS's facing each other and click " search for friends"... if that's what you meant...

( P.S. you rarely get anyone to chat with because the connection only goes 30 feet. The person has to be MAX 30 feet away from you and has to be facing you. It just doesn't happen.

It never happenes to me 'cuz I live in the forest ! )
