Hello. It may be possible possible to use different pages instead of different 
lines. When a visitor adds a line, you can create a new page rather than 
append the text to an existing page, for example [[MyStory.00234]], then 
display the last created page with 
  (:pagelist group=MyStory order=-name fmt=#include count=1:)

To display the full story, use
  (:pagelist group=MyStory order=name fmt=#include:)

I think Fox and/or PowerTools should be able to create new serial name / new 
ticket pagenames.

Alternatively, if it is possible with Fox, it may be even better to store the 
new line to two pages: (1) appended to the end of your full story, like now, 
and (2) replacing the content of a temporary LastLine page which you display 
to the visitors.
