I had one final thought, and I can do this myself if you don't have time.

Now that we're getting more organised, would it be possible to write people's names in their area, maybe underneath their numbers? It would be much easier to see who your neighbours are without having to look at the map, then find the list. If you're too busy, I can do it later on today, but I thought this would be easier for everyone if they want to discuss borders with the people who surround their region.
