I've added test tournament queue. If it's empty, it's not showing up, until you check the "Show all queues" checkbox. Once 4 people (the test queue size) join the queue, a tournament will be created with those 4 players, which is a single-elimination tournament. At that time the tournament queue should clear the players and be able to accept next 4 players.
The "Tournaments" tab shows a list of currently running tournaments and their current results. Once the tournament finishes, the results can be viewed by clicking on the "Load finished tournaments" button in the same tab. At this point, each name in the standings will be a link to that player deck, that was used in the tournament.
