Well.
I would define the chatbox (vgui element) outside the function so I can access it with other functions and hide it when it's not used - show when needed, instead of making it inside a function and recreating it each time.
Then, I would create a function hooked to OnPlayerChat that updates info drawn on the mentioned elements.
