Currently, the discrepancy between confirmed participants (still without a purchased ticket) and actually registered users (purchased ticket) leads to a distorted impression of the size of the event. Even low registration numbers that are visible at an early stage can lead to participants who have already confirmed (but still without a ticket) questioning their participation or waiting until more participants have bought a ticket. This sometimes creates a perception problem: People who have already agreed assume that only a few are taking part — in the worst case scenario, this effect intensifies itself. A feature to hide or flexibly control the visible list of participants or registration numbers would help to avoid this perception.
