We have had a PHP FAQ script developed for us, and the developer is interested in selling it. Basically, I'm just doing a little market research for him, and seeing if there is demand for such a script, and how much you would be willing to pay?

I'll try to get a demo / screenshots up, but basically it has an admin panel, and a user front-end where the FAQs are displayed in categories.
The admin panel has features to add categories, delete categories, edit them, add questions to categories, delete them, edit them... etc.

Please email me directly at mrussell@reflexhost.net if you are interested in such a product.

Regards
Matt
