I recently created a tournament that was meant to be private but I forgot to check "Use Custom List".
I could edit the tournament to correct that but before I noticed the error, a pair not on our custom list had already registered.
Is there a way to remove that specific pair before the tournament starts? I tried sending them a chat message but got no answer.
I ended up cancelling the tournament and re-creating it but would be nice not to have to do this.
