Do you need a license to teach martial arts?

I don't think so. I live in CT, but I take Tang Soo Do karate. I have been taking it for 6 years and I am a second degree blackbelt. I teach karate and I'm on Demo Team. I don't think you need a liscense. After all we have the Free Enterprise System. Go to your town hall of city hall and ask to see the law book or whatever. I am just a kid, so I wouldn't know to much about that.
