Nametags Above Player

Hello. I am trying to work a way to put nametags above players from a string. T$$anonymous$$s then needs to be synced to all players can see it over the network. How would I do that? I'm assuming it's by RPC calls but I am very uncertain how they work at t$$anonymous$$s point. All answers I've found has been outdated with the Network view.

Thank You! - TwoTen
