You can now choose between Free, Paid and Tipping Goal when creating a post once you have uploaded the content. On VXModels you can see the content and the status of the tipping goal. Under contribution statistics you can also see who has paid. You will receive a notification for each tipping and as soon as the tipping goal has been reached.
On VISIT-X, the user only sees the picture as soon as the tipping goal has been reached. It also shows how much has already been contributed. Users who have contributed to the goal are marked separately with a small $ medal.
