Hi there! Michael here.
So, I wrote this plugin for personal use - I'm just picking away at it and adding features only as I intend to use it on my personal site or other projects where I choose to further develop it. There are many testimonial-displaying plugins for Wordpress out there. I'm just dabbling and I like the control. At this stage this plugin is pretty bare bones, so if you want to fork it for use as a skeleton for your own, it's all yours! I'd love to see what you do. Great :). Thanks.
