Thank you for your feedback on this. The instructions for the MapRoulette task said "If the surrounding park isn't mapped, consider adding it, see leisure=park and landuse=recreation_ground", which I interpreted to mean that if the park also contained recreation activities ie playgrounds, sport pitch to use both tags.

I've since read this wiki entry landuse=recreation_ground that states:

"in many cases area is both recreation ground and a park. In such cases usual tagging is to add just leisure=park"

From this I understand that just the tag leisure=park is sufficient, however would it be possible to get clearer guidance on the wiki if you shouldn't use both tags.

Over the months I've been working on this challenge, I would have added this tag to both new and existing tags, and the change sets would have included other additions including playgrounds and sport pitches.

Has the deleted relation for the State Library of New South Wales been replaced with anything? At the moment I can't see anything tagged with amenity=library so this needs to be applied to the buildings or a new relation created

Thank you for the detailed explanation, and happy to defer to you as how the relationship is best modelled.

No, these were separate and below it so I may have tagged the level wrong

Sure I have removed the incorrect value for diet:vegan

I get what you mean, what was I was trying to capture is there is a large roof and the building underneath it is only doesn't take up the full width as you can see in these pictures https://commons.wikimedia.org/w/index.php?search=Killara+station&title=Special:MediaSearch&type=image

Looking through my photos there is a locked gate but it's not clear from the limited pictures I took where the path passes through the ruins. Perhaps it's best I just leave the path with the fixme as I am no longer in Norfolk to resurvey the path.

Thank you for adding these paths, were really handy during a recent trip! When you surveyed this a decade ago were you able to walk through the inside of the church ruins? I was only able to walk around them

This change set has now been reverted and I've added the second identifier to the double mailbox after cross checking my photos changeset/104469432

Well spotted on this, I've reviewed my photos from that survey and I've accidently merged N1 61 with the double. I can revert this next week or feel free to do so on my behalf.
