Hmm.

There's also another site for Ringmoor on its own.

When I was posting my stuff, all three existed. I chose to go for the separate sites for Ringmoor and Brisworthy since they had their specific grid references whereas the combined site had a grid-square-wide reference.

Obviously not satisfactory to have the three and, now that I know a bit better how the system works, I'll be happy to move my stuff around if necessary.
