The members of a regional organisation are divided in two groups:
members that support one or more forms of kite-flying;
members that support all (6) forms of kite-flying
members can be:
A federation of clubs, of which the members (flyers) support one or more forms of kiteflying.
A nation-wide organisation that supports one or more of the forms of kite flying.
The members will be the regional associations
so the maximum number of members will be same as the number of regions
