Here is my first GP website for our Dart League, it is now live with realtime stats for our current season. There is still much to do and will continue to be updated over the coming months.

I setup different headers and menus for each section and used a child theme because i have some custom templates that i needed to use along with some custom functions.
Also appreciate the fact that you included a small grid css file, i was able to use some of the classes for mobile and desktop in other areas of my site while using the grid layout in the header files.
Appreciate the work you put into this Tom i found it easy to work with, lots of customization available with GP Premium.
Will use again for sure.
