PlayerAdded Function help?

Im trying to make a script when a player is added, it changes the name of the player to #1 then #2 for next player to enter then #3 when next player enters and continues on. I know that you would probably use PlayerAdded function and new.Player, but I'm not sure how to make it give the player the number for the name then increase for the next player, help please?

local num = 1

Game.Players.PlayerAdded:connect(function(Player)
	local nm = num
	num = num + 1
	Player.CharacterAdded:connect(function(Char)
		wait() --So the character has time to load fully.
		Char.Name = "#" .. nm
	end)
end)

num in that script will increment by 1 for every Player than joins the game. It will not fill in numbers for Players leave, however, but the characters' names will persist through death.

It is (iirc) not possible to change the name of the Player objects, but you can change the name of the corresponding character Model.

I just tried that, it is impossible. ROBLOX does not allow you to rename player names or character names.
