Which photography challenges organized by Scott Kivowitz have gained the most popularity?

The available content doesn’t list specific photography challenges I’ve organized or rank them by popularity, so I don’t want to make anything up. Most of my community engagement has centered around education, in-person events, and sharing breakdowns of sessions (like surprise proposals), rather than recurring public “challenge” series with tracked stats.

Are you thinking of a particular platform (Instagram, YouTube, email list, etc.) where you saw one of my challenges?
