I can't figure out how to connect with my friends
Tell them to go on world chat at the same time as you. When you speak in world chat you can click on each other's names and an option to add the selected person as a friend will appear.
If the chat is moving too fast for you to tap on you're friend's name, simply press the pause button on the bottom right of the chat screen. This is stop incoming messages allowing you to easily find your friends
