I've approved this though, though i've changed the time for signups due to what you've wrote and have a question for you.
You've wrote the tournament is for the day after tomorrow 08/11/2021 at 8pm GMT, it's better to have the signups right before the Tournament is due to start, so i've changed the signups time to tomorrow at 8pm GMT. That way players can start signing up 30 minutes before the Tournament starts.
Generally speaking, we don't open signups much longer than right before the Tournament is due to begin as this can cause players to signup and forget or maybe they have something in their life they must attend to and they forget to leave.
So, you've wrote:
And is All vs all, not 1 vs 1 .
How exactly is this going to work?
The format for Tournaments are players signup either alone, or in teams, then once there are enough players, you end the signups by pairing the players, and the Tournament begins.
If you intend to create a Free For All match with multiple players, this would not work in a TUS Tournament format.
