Forgive me, I'm struggling with the translation - does this mean that anyone with a reserved status on this list now has a place or does it simply mean they are hoping for a place to become available?
After you register yourself for the event, there is a period of 14 days were your ticket is reseved for you. If you pay within these 14 days, you have your ticket secure. If you do not pay within the timeframe, the reservation of the ticket ends and you are not guaranteed a ticket anymore. If there are still tickets available and you pay afterwards, you get your ticket, but should all tickets be sold out or reserved you do not get any.
Everyone who has a green status above has a ticket paid, the yellow status means he has not paid yet but his ticket is still reserved.
