I found this plugin after being asked to create a testimonial page on a wordpress website. I wanted it to be as easy as possible for the client to get testimonials straight from the website and all she would have to do was approve them and they would show up on the page. GC Testimonials is really easy to install and use. The plugin uses shortcodes so once installed its just a matter of adding the shortcode to the designated page for testimonials. You can also add an easy to use form for customers to submit their testimonials to you.
