I kinda do. I (among about three other home study courses) use the American Modern Jujutsu course, whom the President of is a Yoshin ryu Black belt.
I figure it can't hurt to see what everyone is up to. besides my home courses (jujutsu, Tushka-homa, taijutsu), I study Ideta ryu Bujutsu, shin ryu Aikido, Ninjutsu, and Kokkar Kempo at Dojos here in WA.
