For example: I post:
Next poster:You find yourself in a wide clearing. There is a pile of leaves.
>_
Next poster:> Move leaves
... and so forth, only with more embellishment as appropriate.Under the leaves you find a banana peel.
>_
I recommend saving a placeholder first, so that if someone comes along while you're writing they'll know you intend to add to it already.

A Crooked Path
You are walking along a stone path in a grassy valley. The path winds along the nadir of the valley, taking several turns along the way. The path continues north. To the east is a dirt path into a forest. To the west, an impassable mountain ridge. To the south, another dirt path leads to the small beach where you arrived.
There is a printed leaflet here.
