I went to the rulebook. The very first line reads: "Each Federation which is affiliated with the IWWF shall have the right to select a team of skiers to represent their Federation in the World Championships."
Any new organization would have to be recognized by the USOC in order to be affiliated by the IWWF. Same probably goes for scores to get onto the world rankings list or into the worlds as a non-team member.
Also, rule 16.02 reads "Records may be set only at tournaments homologated as a Record Capability Event by the IWWF, a Confederation, a Federation, or the Tournament Council of the IWWF." Any record set at a non-USAWS sanctions event would not be recognized as an IWWF world record.
And @Jody_Seal while we are "chatting," do you still have that yellow 197 for sale?
