Tickled Pink - Testimonials Rotator Setup
This theme uses the Testimonial Rotator plugin in the Front Page Four section, which can be obtained here or by searching in Dashboard>Plugins>Add New.
Once installed you’ll have a new Testimonials tab on the left in your WordPress dashboard.
You’ll add all your testimonials there and then configure the widget as you see below.
A detailed step-by-step tutorial can be found directly from the plugin developer here: Getting Started with the Testimonial Rotator Plugin.
