I've been looking for this for days, i really need this.

Is their a way to make appear text in every instance of
my page.
I'll give a little example:
Let say 10 ppl have my page on their screen,on my page their's a text box. Let say if one of them go put something
in the text box and press submit(or something)everybody will
have the text appear in their textbox?

THEIR MUST BE A WAY.........................I HOPE SO!
