@W1slicer I am a not so bright, a say that about me all the time :D but to this maybe i have a different point of view then you like it seams. Only in the US at this moment it was decided prompt alone is not enough, rest of the world is not clear at this moment about it. ( maybe most of the world i don't keep track on that perfectly). But it nicely tracks the generation year & who made it. It may be just a not functional stamp at this moment bud depending on the country or law change it may be different.
In other words who knows what will the future bring, better have a meaningless copyright sing on it now when i make the pictures then later to remark all pics if something changes. Like i said agree that not so bright, so my point of view is also not so ideal :D
