THANK YOU!
All I needed.
I'm going to sign up.
I was checking Wikipedia...
Sounds great!
Before you do, make sure it's not a bullshit school. There are schools that only do point fighting because it's not a liability and it gets the soccer moms in the door, especially TaeKwonDo, giving karate a reputation as being soft.
Take Kyokushin Karate(Japanese Full-Contact) or Goju Ryu(traditional Okinawan karate).
Also Shorei-Ryu and SeidoKaikan are good styles.
Most of the karate fighters that are successful in events like K-1 are Kyokushin, because they do a lot of real sparring (gradually of course).
