I notice you removed the FIXME from osm.org/node/379690999/history - can you explain why?

I haven't surveyed properly yet, but although this postbox is physically present, I believe it's no longer in use.

Thank you for this useful edit. I notice you have added a way for St Andrews Church at osm.org/way/321241861 but kept the existing node at osm.org/node/411503720 so the map now contains two churches close by. You might want to delete the node and merge in the tags describing the religion and denomination on to the way.

Also, I haven't visited MK Central station in a while, but I'm surprised there's a toilet between the two bus lanes at osm.org/node/3279749144 !

Thanks again for adding more information to the map,
Tom
