The IUKF supports its member's participation in tournaments, both inside and outside the organization.  The Board feels that experiencing other rules, and competing with other schools, organizations and styles helps give the participant perspective that allows a fuller understanding of our own style.
Regarding personal disputes between practitioners, the IUKF does not take sides.  It is up to the individuals involved to sort things out for themselves.  The more senior the people involved, the better they should be at solving disputes, and putting matters in perspective.
