Hi, i have doing kyokushin for about 2 weeks, i have a questions, hoping here on MAP some knowledgeable karateka will be able to answer. 1. There are quite a few different kyokushinkai organisation around. IKO, IKO2 (WKO), IKO3, IFK etc. Which of these organisations is the largest? 2. If one organisation holds a kyokushin tournament, are members of other kyokushin organisation allowed to compete in that tournament? 3. If i progress in kyokushin, say if i get into 6kyu in a WKO dojo, and quit. then later join a IKO1 dojo. will that IKO1 dojo accept me as a 6kyu or a beginner.
