REPLY to your message (For some reason I coulden't send you areply)
What you do is you is after registering my friend code and I register yours, we both go down in the bottom floor of any pokemon center and the woman near the counter door(two ladies will be there, any will do) will ask if you would like to connect to wifi, say yes to all of the questions after that. Once you connect, you should see invite and disconnect. If someone on your pal pad is on, it should say there current wifi status(standing by, trading, etc.) once you see someone, and they invite you(there will be a trade/battle sign after there name) apply for it and whalla! You are trading/battling.
P.S Erase this after reading....for some reason the Pm's woulden't work.
