the testimonial site will be in WP (the product/cart site is on a non-related site in Pinnacle Cart. which testimonial system is terrible).
i want customers to be able to post their images with their text.
i sell rafts, kayaks, accessories... there has to be some kind of order/categories so new potential customers can easily find the product they're thinking of purchasing and read the reviews. it can't be just top down and user has to scroll through comments to find their product.
i've made a bunch of (excellent) WP sites with Pages only. i've never used Posts.
i don't know if i should create a WP Discussion Site and make a forum for each product. or would Posts and with categories be better?
