Everyone here has List Me on wild.computer on in Wild's settings, which it is unless they turned it off. Tap Add beside someone you know and Wild opens with a contact request ready to send. They see it the next time you're both online, and you're contacts once they accept. Open a person to see who they know here: friends of friends are often friends.
Nothing happens when you tap Add? You need the Wild app on this device. To leave, or to come back, use the switch under Settings in Wild; the listing follows your name, picture, devices and contacts as they change.
