The group phase for the StarCraft II compo has started, you can find more details HERE. There's also a timeschedule at the news section of the compo overview.
The group stage will be played from 8 to 14 with a 1h break at 12, this will mean you have 7 hours to play all your matches, which should normally be sufficient.
After the group phase, the top 4 of each group will continue on into the Winner's Bracket, place 5 and 6 are placed into the Loser's bracket.
If there are any problems / questions, please come to the compo desk.
