I would consider myself somewhat of a regular, so if I haven't seen it I really doubt it's that easy to find! Sometimes it's just one post in many and can be easy to miss around all the amazing photo updates. Also sometimes people are just plain cranky on here ?TBH, people who aren't regulars miss out on documents and those get lost in the discussion- even I sometimes have to go digging around for documents.
IMO it would be better if the project page had some sort of subsection that collected planning document links for easy access.
I made that request for the Application Docs to be included on the Database page in the website thread but it never got a response.
