Forum:Tourney Help? (WC2009)

Today (4/4/10) I finally got my "stated" 15th Lv2 Duelist for WC mode in World Championship 2009, but I can't seem to start the tournament. Can anyone help me out? I believe I already have 15 Lv2 opponents for the lv2 tournament. Are there any other requirements? If so, what are they? If there are no other requirements, then who do I talk to or what to I do to start the tournament?
