The review script is really best customized to a specific item to be reviewed. For example, if I created one for speakers, someone who wanted to use it for cars would have a hard time adapting it. Plus, you're better off starting with a review script and adding a comment feature than starting with vB and adding a full-scale reviewing system.
As for the news system, thats feasable. The only thing thats sort of "iffy" is the multiple page break, but it is possible. My only concern is that some people would want a different setup of the news script than someone else. I'd like to create a universal hack...something everyone can use to its fullest
