With regard to my Main reason for my five star rating, it is hard to choose between Customer Support and the excellent design of the Bookstore Kalium theme – because both are equally excellent. But ultimately Ylli at Kalium has prevented me from pounding my head into the wall more than I would have otherwise, so Ylli wins that contest. I have only so-so experience with WordPress. I build a site every 2-3 years and feel like I have to relearn it from scratch every time. So even with this well designed theme it took a few days of frustrating diligence before I started to get it. (I highly recommend a clean install - get rid of that old stuff first) But once I began to grasp the theme's functionality, (with Ylli's help when I got stuck) it all made sense and I am increasingly happy with this theme's possibilities. The Bookstore theme is great. I love my new site and it is getting extremely positive response.
