I am wondering if you should add to your how to (and everyone creating an initial review page should add) a couple lines at the end of the review stating:
To add a review please start your post with "I give this tree nursery X out of 10 acorns"
To see a listing of all the reviews like this one please see here https://permies.com/wiki/76171/seed/official-permies-Seed-Plant-Source
That way everyone can know how to do the review and how to find the whole list of reviews.
Also can you add your how to to the review grid? The way people will see how to add entries to the grid?
