I think this is an excellent idea, as much as i admire the work that people put in to creating fan edits of movies, (and this is just my view) I was disapointed that GL wasnt as successfull this time around with the Prequel movies.

and although many people have come up with impressive edits they are all limited by what was originally filmed.

I think a forum for people to work on new scripts or novels for the prequels would be great and allow for more exploration of the star wars mythos and essentially unlimited imagination.
