Shamed into joining by CRHIt's an England & Wales organisation for protecting the green lanes that we can use in UK
Obviously you can be from anywhere in the world and join as you would still have access to them were you to travel to UK, Scotland is different.
I'm sure your earlier post suggested the same, they do an excellent job of fighting for our rights to use the lanes and keeping them open. It's not expensive and you get access to TrailWise which is very useful.
