Florian,
Thank you for sharing this question. I guess many of you know why we started out with the hunt-in-your-hometown approach from day 1. We sticked to that in the first few years, but started to be more flexible as the community grew. However, we keep receiving questions for even more flexibility. I saw @Claudiane.OP ask for the same a few days ago.
I think we have to see how we can offer this flexibility automatically to hunters that 1. know how the platform works, 2. travel alot and want to document while traveling.
I love your proposal of at least offering the ability, when meeting a certain level of usage and understanding of the platform.
@Noa_Heutz is preparing a research among all groups of users on the platform. And he’ll improve different parts of Street Art Cities afterwards, based on outcome of the research. This should definitely be involved. Good point Florian, please hang in there while we try to improve and be on the look out for an e-mail from Noa!
