I'm sorry about the first comment, I didn't checked the wiki before
commenting and I wasn't aware of the "editing war" there.

On the other hand, I think this "map gardening" across the half of UK
without local knowledge it isn't the best way to improve map quality. Maybe
it's better not to start doing that kind of map gardening until the wiki is
clear?

Best regards,
Alejandro
