I use this plugin for our amateur rugby club website and I have to say that it is really helpful. Before, we had to change the website every week to show the next upcoming game. With this plugin you just type them in once, and all the rest works like a charm.
I also had some mail conversations with Mark (the developer) and he is very kind and cooperative. I think the last update (3.5.2) fixed a few things I didn't like too much before (like date formatting).
The only thing I could criticize is the default design of the widgets, but apart from that, I really love this plugin.
Keep up the good work Mark!
