ok, so i managed to get something up and running with Grav. I had to hack about with the antimatter theme to make it do what i wanted, but it works.
I must say I'm impressed so far with Grav, especially the responsive operation, which appears to work well on mobile devices I've tried so far.
Please keep working on, and improving, the documentation. It's essential for anyone like me new to the project.
Well done everyone and keep up the good work!
