Hi,
Well, it is not difficult to create a threaded view.
I wrote a few discussionfora in the past that do this, but they were
written in JAVA, not PHP.
It also offered the option to 'link' your response to multiple other
articles.
It boils down to storing parentid of a response, like Rik explained,
using recursive logic. (I sidestepped the real recursive logic by using
an alternative algoritm, but that was because I was having trouble with
the multiple parents.)
If you are going to write your own threaded forum that uses multiple
parent, I will gladly share my experience with you if needed.
Regards,
