Text box to add messages to.

I’d like to make a text box on the GUI that allows me to send messages eg: You hit player X, You killed player X, You can’t do that, etc to a alert type window. After so many seconds the messages disappear and if you are receiving a lot of messages it will scroll. I had this working in DF-GUI using AddControl then Destorying the control after seconds but can’t figure out how to make it work in UGUI. Any help would be greatly appreciated.

Use a GUI.Label inside a GUI.Box.
