Welcome to the forums Lax93. If you want to add people on Mario Strikers Charged I suggest you look at this thread if you are living in the US: http://www.wiichat.com/mario-striker...-exchange.html or this thread if you are in Europe: http://www.wiichat.com/mario-striker...ge-europe.html . Go to the last page of these threads to look at the latest members who want to be added. Make sure you private message the people you want to add, so they can add you in return.
Just letting you know that the Mario Strikers Charged friend code is different to the Wii friend code (incase you weren't aware).
