Tournament Host Powers
I know there's a lot of ideas out there that make up parts of this entire idea, but I believe this is a coherent grouping of them, with added ideas tacked on.
Reason for this idea: The Game Host has shown improvements and added powers, but the Tournament Host has not, and this stagnation of improvements have made tournament hosting quite difficult.
Powers of the Tournament Host to be given through settings and allowed for the player to check:
To boot players, even if not deemed inactive by the settings themselves. (Disorderly conduct, dishonorable plays, etc.)
To decline players who accepted the invite (A blacklisted player got in by being invited by another player in the tournament, cases like that.)
To allow "broadcasts" to be sent to the chats of the individual games (perhaps only for smaller tournaments)
To control the bracket. (Default to not showing victors until Host allows it.)
To "pull the plug" and delete the entire tournament while its ongoing.
