I'm on the yearbook team (which is being run by @enaz), and Manifold has been quite a phenomenon at Proof this year. To count for this market, the exact phrase "Manifold Markets" (with both Ms capitalized) must be written prominently enough that almost all people reading that page would be expected to see it; it can't be hidden in a tiny font somewhere. Text in images does not count — in particular, a picture of someone wearing a Manifold Markets shirt would not be sufficient for this market.

General policy for my markets: In the rare event of a conflict between my resolution criteria and the agreed-upon common-sense spirit of the market, I may resolve it according to the market's spirit or N/A, probably after discussion.
