Re: Can you add friends through Gamecenter?
Yes.
- Click on the GameCentre icon on your ipad/iphone while signed in to Gamecentre
- Click on "Friends" from the menu that runs horizontally along the bottom of the screen
- In the new window that opens up, on the top-left corner of the screen there will be a blue "+" icon next to the word "Friends". Click on the "+" icon
- This will open up a new box with "Friend Request" as the heading. Enter the email address or GameCentre nickname/ID of the person you want to add and then click "send".
For a list of players who are currently looking for friends/neighbours then see this thread.
