I would like to add this function. For example, one user places a task on the map (to make an overview of the Eiffel Tower) and a reward for this 50 coins and other users can try their hand and receive a reward.
It sounds ideal, when you going to holidays you choosing places that you want to visit, so now you can get back some money during your relaxing. But who will decide which review is better if you place an order to review... it shouldn't be a community because you paying.
