[Plugin: Collision Testimonials Shortcode] Collision testimonials plugin

Upon researching plugin compatibility, I have also come to realize that the plugin no longer exists. The link within the release that I have on my site leads to Bestimonial http://bestimonials.backendlabs.com/. It looks like he changed it to a paid plugin without any mention of such.
Here is a single post about the two on his support forum for the paid version. http://support.backendlabs.com/discussions/bestimonials/58-how-is-bestimonials-different-than-collision-testimonials
