This extension is really great. I use it my two websites, it was really easy and fast to install and customize.
I had small issue with my template and pop-up windows, it was handle by support in no time.
News calendar is just what I was looking for. I spent few weeks trying to adjust some other extensions to do what this calendar do. It was very easy to translate and to change the look of module by switching images. Installation, translation and upgrading images took me just 20 minutes! I like this extension so much that I registered just to write review. Thanks Jesus.
