Disable discussion window at the end of every page

[kaja.a]

It possible to disable discussion window at the end of every page?

I know it is possible if I add __ NODISCUSSION __ in source editing mode, but I have to do this for every page manully. Is there any code I can write in Common.css, to disable discussion window for all the pages?
