How do I get the user's name on a GUI?

I'm working on a social network inside of ROBLOX, and I was wondering how I can get the local player's name on the GUI text..Any ideas?

gui = PATHTOGUI

game.Players.PlayerAdded:connect(function(player)
gui.Text = player.Name
end)

Depends on which kind of GUI but if it is a Gui that has a text in it,you try to find which is the text you want to put the person's name in
