Hi. I used to practice Shotokan a few years ago and my dojo was affiliated to SKIF (Shotokan Karate-Do International Federation), and actually I participated in a some tournaments organized by that federation, and I got my 8th Kyu certificate guaranteed by SKIF. Now I wanna go back to Shotokan, but I found some Dojos affiliated to ISKF (International Shotokan Karate Federation). Anyone knows if SKIF became ISKF, or if they are different federations? Greetings
