Reaching participants: Open Lab's three invitation types, and how they work alongside Prolific and other panels

Open Lab's Invitations page has three tabs: public links, direct invitations and tracking links. A panel such as Prolific or Mechanical Turk is not an alternative to any of them: the panel supplies the sample, and the invitation link is what it points at. What each invitation type is for, the two mechanisms every panel integration is built from, and the settings that break a round trip.
