Number 8 for me please.
I have some questions of technical/organizational nature:
Is there a time limit until someones reservation is nullified in case he/she does not manage to submit anything?
Each tile has 4 borders and each of these borders is shared with another tile. Which of the borders(left, right, up, down) are part of the tile we do and which shall be part of the adjacent next tile?
If there is "nothing" in the space above/below/next to our tile, may we draw freely over the background color?
