The project and the developer should be given certain dates in the calendar and all investors and ordinary users should know about it. Everything should be transparent.
Maybe all this is written somewhere, we just can not find. Why are team members silent and not answering these questions?
Of course I would like to hear more specific dates and numbers from the project team. I think that silence is not the best option in this case. But maybe the ArtPro project team is just very busy right now? let's wait a bit!
