Hi! To be able to ask for someone's friend code, you have to click on this button: . You can find it on the right of the posts of most people, and also in their profiles. However, you'll find you won't be able to do that at the moment because you need to add your own code to the system first. This works both ways - if someone hasn't added their code, you won't be able to ask for it.
Here's how to set up your friend code: Step 1: Click on "My Friend Codes" on the left hand side of ACC. It's underneath "My Buddies", and on top of "My Favourite Boards." Step 2: There should be a title that says "My WiFi Games and Settings." On the right of that title, there should be a link that says "Edit." Click on Edit. Step 3: You'll be taken to a list of games that have Wi-Fi capability. What you need to do is scroll down and find "Nintendo 3DS Code." It's in alphabetical order. Type the Friend Code for your 3DS in the box next to it (including the hyphens), click submit at the bottom, and you're done! If you have more than one 3DS code because you have more than one console, you can use the other boxes. I recommend you enter your code into all three of the boxes (1, 2 and 3) just in case you play with someone who has entered their code in 2 or 3. You see, if you don't have a code in 2 or 3, you won't be able to see another member's 2 and 3.
I hope I made sense! A good place to go from here would be the NL WiFi Lobby. Happy WiFi-ing!!
PT me if you need help on ACC! :)
