The games are going to be coordinated by the tournament director. The brackets will be finalized the day of the tournament once signups have closed and the first round games will be played.
The tournament starts at 14:00 GMT on Saturday. Players who do not show up for the start of the tournament will be considered no-shows and the brackets will be adjusted accordingly.
The tournament will hopefully be a 1 day tournament lasting 5-6 hours. This means that games and rounds should be played as soon as both players are available which should be quickly since everyone will need to be present at the start of the tournament. The sources of delays will be difference in game times for matches between players as well as player breaks for necessities.
Unless there is a large influx of people tomorrow the tournament will stay with only two brackets with Bracket 1 being the top 16 seeded players and everyone else being in Bracket 2. Challonge currently displays 3 brackets only due to a limitation in the interface but that will be remedied on the day of the tournament.
