How often are you waiting on that 10th player? It's happened to me, it's happened to you, hell, I'm sure it's happened to Sinatra too.
Today I'm rolling out a new in-game command for PopFlash Supporters: !extend
It'll delay the warmup from ending and give you an extra few minutes to allow your friend to figure out how to open the CS:GO console.
Hope you're all safe and sound out there. More soon.
