Lol , ok UK makes sense now
That is why you like to explain things in every bit detail.
But , you still did not answer the question,
Why , why do you want this functionality?
What is it that you are trying to "hide" ( not display ) in original article ,
you do know that you have Intro and full text and you can always
hide Intro text in full page view
this way your intro text can be anything else , and you page view ( full text ) can be something totally different and you dont have to make 8 articles instead of 4
I dont know any other extension that looks like YJME and links to something else other than what is displayed without reconstruction,
Image sliders yes they can do this but not newsflash modules.
