head on over to True Dungeon Forum and look for your group. http://www.truedungeon.com/forum?view=category&catid=591 I recommend searching for the event id TDAXXXXXX, though searching for day and time should work as well.
Though obviously not a requirement of playing, it can greatly save you some time and grief by finding your fellow players in the time slot you have. You may be able to sort out difficult of play, character choices and see if anyone has tokens to help you with your build. You might even learn some clues about the adventure(s) you are about to partake in.
See you in the dungeon.
