you can also just click the TOURNAMENTS link on top of your KDice window

big tournies start being available for joining 1 hour in advance, freerolls start 30 minutes in advance, you will see a little box appear on your KDice screen (upper right: above map, about the same place where the end of the month timer is situated now)

You can click join , you will see it says joined from then on

if you dont see the join button and you think a tourney is sheduled, just refresh, it might appear then

when the tourney starts, you will get a popup box, saying click to go to your tourney table, do that to enter the tourney

if you don't get the popup, go to change table and change to the tourney table tab and pick a table there + switch to your own table after you see in the player list at what table you were sat (the little number next to your name)
