That challenge was sent 10 days ago. They expire after around 1 week. I suggest you negotiate with the admin of the opposite team for a new start date, if they agree to still play the match.
Clubs can claim a win 3 days after a valid challenge is posted here, if it's not accepted. I haven't seen that claim yet, though.
TCMAC GAIUS IULIUS CAESAR 2024/2025 GE R3: The Ge-Winner vs. The Chess Warlords - TCW
Challenge:

The challenge cannot be found, I checked upcoming matches and I can't find the match meaning that someone has cancelled the challenge (I think it was someone from The Chess Warlords-TCW)
I have created a new challenge:

I don't think it's possible for both clubs to get the minimum of 10 players in less than 3 days
Especially the fact that I didn't know that the challenge got cancelled.
Is it possible if you can make a decision about this or not?
