Currently you have to check a box that says you'll be at least 18 to purchase tickets at manifestconference.net for the upcoming Manifold conference. However, @saulmunn has expressed to me that the Manifest organizers want minors to be able to attend, and are attempting to work out the logistical/liability issues involved!

This market resolves once it's clear what the outcome will be (>98% confidence from me or Manifest organizers), and will re-resolve if there is a surprise twist.

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.
