How do you put your roblox group rank above your head that say dev or owner or something like that?

Like if you are the developer of something and you were... Then how do you make it pop up on top of you like a nametag so people can know if they are the developer of the game?

For this what we need to do is add a BillboardGui to a player's character every time they spawn.

function onSpawn(character)
    g = Instance.new("BillboardGui", character.Humanoid.Head)
    -- The rest
end

And we need connect this to a player's character spawn event every time they enter the game.

game:GetService("Players").PlayerAdded:Connect(function(newPlayer)
    -- Connect to player's character added event
end)

For this we can use Player.CharacterAdded, and when Connecting just feed it our onSpawn function.
