What I want to do is implement a buddy system so two or more people can only do things to each other if they are buddies. How they would become buddies is by both pressing an option in a menu. So one person would send a buddy request in the menu to another person, and the other person would have to send one back to the person who sent it. After they do that, they could teleport to each other, kill each other with the menu, etc.
