Ok i almost succeed
1 download the demo into sgf
2 upload the sgf into library
3 open the sgf
4 create a review
Checked the list of demos in my profile: job done!
Still a problem, when i want to change the name of this duplicate demo of the original demo (using game information )
Any idea why and how ?
I found another topic/request on this.
Can this be solved or is there another way to get my duplicate demo?
